INA21x Voltage Output, Low- or High-Side Measurement, Bidirectional,
Zero-Drift Series, Current-Shunt Monitors
1 Features
3 Description
•
•
The INA210, INA211, INA212, INA213, INA214, and
INA215 are voltage-output, current-shunt monitors
that can sense drops across shunts at common-mode
voltages from –0.3 V to 26 V, independent of the
supply voltage. Five fixed gains are available: 50 V/V,
75 V/V, 100 V/V, 200 V/V, 500 V/V, or 1000 V/V. The
low offset of the zero-drift architecture enables
current sensing with maximum drops across the
shunt as low as 10-mV full-scale.

8 Detailed Description
8.1 Overview
The INA210-INA215 are 26-V, common-mode, zero-drift topology, current-sensing amplifiers that can be used in
both low-side and high-side configurations. These specially-designed, current-sensing amplifiers are able to
accurately measure voltages developed across current-sensing resistors on common-mode voltages that far
exceed the supply voltage powering the device. Current can be measured on input voltage rails as high as 26 V
while the device can be powered from supply voltages as low as 2.7 V.
The zero-drift topology enables high-precision measurements with maximum input offset voltages as low as
35 µV with a maximum temperature contribution of 0.5 µV/°C over the full temperature range of –40°C to 125°C.

8.3 Feature Description
8.3.1 Basic Connections
Figure 23 shows the basic connections of the INA210-INA215. The input pins, IN+ and IN–, should be connected
as closely as possible to the shunt resistor to minimize any resistance in series with the shunt resistor.

Figure 23. Typical Application
Power-supply bypass capacitors are required for stability. Applications with noisy or high-impedance power
supplies may require additional decoupling capacitors to reject power-supply noise. Connect bypass capacitors
close to the device pins.
On the RSW package options, two pins are provided for each input. These pins should be tied together (that is,
tie IN+ to IN+ and tie IN– to IN–).
8.3.2 Selecting RS
The zero-drift offset performance of the INA210-INA215 offers several benefits. Most often, the primary
advantage of the low offset characteristic enables lower full-scale drops across the shunt. For example, nonzero-drift current shunt monitors typically require a full-scale range of 100 mV.
The INA210-INA215 series gives equivalent accuracy at a full-scale range on the order of 10 mV. This accuracy
reduces shunt dissipation by an order of magnitude with many additional benefits.
Alternatively, there are applications that must measure current over a wide dynamic range that can take
advantage of the low offset on the low end of the measurement. Most often, these applications can use the lower
gains of the INA213, INA214 or INA215 to accommodate larger shunt drops on the upper end of the scale. For
instance, an INA213 operating on a 3.3-V supply could easily handle a full-scale shunt drop of 60 mV, with only
100 μV of offset.

8.4 Device Functional Modes
8.4.1 Input Filtering
An obvious and straightforward filtering location is at the device output. However, this location negates the
advantage of the low output impedance of the internal buffer. The only other filtering option is at the device input
pins. This location, though, does require consideration of the ±30% tolerance of the internal resistances.
Figure 24 shows a filter placed at the inputs pins.

Figure 24. Filter at Input Pins
The addition of external series resistance, however, creates an additional error in the measurement so the value
of these series resistors should be kept to 10Ω or less if possible to reduce impact to accuracy. The internal bias
network shown in Figure 24 present at the input pins creates a mismatch in input bias currents when a
differential voltage is applied between the input pins. If additional external series filter resistors are added to the
circuit, the mismatch in bias currents results in a mismatch of voltage drops across the filter resistors. This
mismatch creates a differential error voltage that subtracts from the voltage developed at the shunt resistor. This
error results in a voltage at the device input pins that is different than the voltage developed across the shunt
resistor. Without the additional series resistance, the mismatch in input bias currents has little effect on device
operation. The amount of error these external filter resistor add to the measurement can be calculated using
Equation 2 where the gain error factor is calculated using Equation 1.
The amount of variance in the differential voltage present at the device input relative to the voltage developed at
the shunt resistor is based both on the external series resistance value as well as the internal input resistors, R3
and R4 (or RINT as shown in Figure 24). The reduction of the shunt voltage reaching the device input pins
appears as a gain error when comparing the output voltage relative to the voltage across the shunt resistor. A
factor can be calculated to determine the amount of gain error that is introduced by the addition of external series
resistance. The equation used to calculate the expected deviation from the shunt voltage to what is seen at the
device input pins is given in Equation 1:
(1250 ´ RINT)
Gain Error Factor =
(1250 ´ RS) + (1250 ´ RINT) + (RS ´ RINT)
where:
•
•

RINT is the internal input resistor (R3 and R4), and
RS is the external series resistance.

Device Functional Modes (continued)
With the adjustment factor equation including the device internal input resistance, this factor varies with each
gain version, as shown in Table 1. Each individual device gain error factor is shown in Table 2.

The gain error that can be expected from the addition of the external series resistors can then be calculated
based on Equation 2:
Gain Error (%) = 100 - (100 ´ Gain Error Factor)
(2)
For example, using an INA212 and the corresponding gain error equation from Table 2, a series resistance of
10 Ω results in a gain error factor of 0.982. The corresponding gain error is then calculated using Equation 2,
resulting in a gain error of approximately 1.77% solely because of the external 10-Ω series resistors. Using an
INA213 with the same 10-Ω series resistor results in a gain error factor of 0.991 and a gain error of 0.84% again
solely because of these external resistors.

8.4.2 Shutting Down the INA210-INA215 Series
While the INA210-INA215 series does not have a shutdown pin, its low power consumption allows powering from
the output of a logic gate or transistor switch that can turn on and turn off the INA210-INA215 power-supply
quiescent current.
However, in current shunt monitoring applications. there is also a concern for how much current is drained from
the shunt circuit in shutdown conditions. Evaluating this current drain involves considering the simplified
schematic of the INA210-INA215 in shutdown mode shown in Figure 25.

NOTE: 1-MΩ paths from shunt inputs to reference and INA21x outputs.
Figure 25. Basic Circuit for Shutting Down the INA210-INA215 with a Grounded Reference
Note that there is typically slightly more than 1-MΩ impedance (from the combination of 1-MΩ feedback and
5-kΩ input resistors) from each input of the INA210-INA215 to the OUT pin and to the REF pin. The amount of
current flowing through these pins depends on the respective ultimate connection. For example, if the REF pin is
grounded, the calculation of the effect of the 1-MΩ impedance from the shunt to ground is straightforward.
However, if the reference or op amp is powered while the INA210-INA215 is shut down, the calculation is direct;
instead of assuming 1 MΩ to ground, however, assume 1 MΩ to the reference voltage. If the reference or op
amp is also shut down, some knowledge of the reference or op amp output impedance under shutdown
conditions is required. For instance, if the reference source behaves as an open circuit when is not powered, little
or no current flows through the 1-MΩ path.
Regarding the 1-MΩ path to the output pin, the output stage of a disabled INA210-INA215 does constitute a
good path to ground; consequently, this current is directly proportional to a shunt common-mode voltage
impressed across a 1-MΩ resistor.
As a final note, when the device is powered up, there is an additional, nearly constant, and well-matched 25 μA
that flows in each of the inputs as long as the shunt common-mode voltage is 3 V or higher. Below 2-V commonmode, the only current effects are the result of the 1-MΩ resistors.

8.4.3 REF Input Impedance Effects
As with any difference amplifier, the INA210-INA215 series common-mode rejection ratio is affected by any
impedance present at the REF input. This concern is not a problem when the REF pin is connected directly to
most references or power supplies. When using resistive dividers from the power supply or a reference voltage,
the REF pin should be buffered by an op amp.
In systems where the INA210-INA215 output can be sensed differentially, such as by a differential input analogto-digital converter (ADC) or by using two separate ADC inputs, the effects of external impedance on the REF
input can be cancelled. Figure 26 depicts a method of taking the output from the INA210-INA215 by using the
REF pin as a reference.

8.4.4 Using The INA210-INA215 with Common-Mode Transients Above 26 V
With a small amount of additional circuitry, the INA210-INA215 series can be used in circuits subject to transients
higher than 26 V, such as automotive applications. Use only zener diode or zener-type transient absorbers
(sometimes referred to as Transzorbs)—any other type of transient absorber has an unacceptable time delay.
Start by adding a pair of resistors as a working impedance for the zener; see Figure 27. Keeping these resistors
as small as possible is preferable, most often around 10 Ω. Larger values can be used with an effect on gain that
is discussed in the Input Filtering section. Because this circuit is limiting only short-term transients, many
applications are satisfied with a 10-Ω resistor along with conventional zener diodes of the lowest power rating
that can be found. This combination uses the least amount of board space. These diodes can be found in
packages as small as SOT-523 or SOD-523.

Figure 27. INA210-INA215 Transient Protection using Dual Zener Diodes
In the event that low-power zeners do not have sufficient transient absorption capability and a higher power
transzorb must be used, the most package-efficient solution then involves using a single transzorb and back-toback diodes between the device inputs. The most space-efficient solutions are dual series-connected diodes in a
single SOT-523 or SOD-523 package. This method is shown in Figure 28. In either of these examples, the total
board area required by the INA210-INA215 with all protective components is less than that of an SO-8 package,
and only slightly greater than that of an MSOP-8 package.

8.4.5 Improving Transient Robustness
Applications involving large input transients with excessive dV/dt above 2 kV per microsecond present at the
device input pins may cause damage to the internal ESD structures on version A devices. This potential damage
is a result of the internal latching of the ESD structure to ground when this transient occurs at the input. With
significant current available in most current-sensing applications, the large current flowing through the input
transient-triggered, ground-shorted ESD structure quickly results in damage to the silicon. External filtering can
be used to attenuate the transient signal prior to reaching the inputs to avoid the latching condition. Care must be
taken to ensure that external series input resistance does not significantly impact gain error accuracy. For
accuracy purposes, these resistances should be kept under 10 Ω if possible. Ferrite beads are recommended for
this filter because of their inherently low dc ohmic value. Ferrite beads with less than 10 Ω of resistance at dc
and over 600 Ω of resistance at 100 MHz to 200 MHz are recommended. The recommended capacitor values for
this filter are between 0.01 µF and 0.1 µF to ensure adequate attenuation in the high-frequency region. This
protection scheme is shown in Figure 29.

To minimize the cost of adding these external components to protect the device in applications where large
transient signals may be present, version B devices are now available with new ESD structures that are not
susceptible to this latching condition. Version B devices are incapable of sustaining these damage causing
latched conditions so they do not have the same sensitivity to the transients that the version A devices have,
thus making the version B devices a better fit for these applications.

9 Application and Implementation
9.1 Application Information
The INA210-INA215 measure the voltage developed across a current-sensing resistor when current passes
through it. The ability to drive the reference pin to adjust the functionality of the output signal offers multiple
configurations, as discussed throughout this section.

Figure 30. Unidirectional Application Schematic
9.2.1.1 Design Requirements
The device can be configured to monitor current flowing in one direction (unidirectional) or in both directions
(bidirectional) depending on how the REF pin is configured. The most common case is unidirectional where the
output is set to ground when no current is flowing by connecting the REF pin to ground, as shown in Figure 30.
When the input signal increases, the output voltage at the OUT pin increases.
9.2.1.2 Detailed Design Procedure
The linear range of the output stage is limited in how close the output voltage can approach ground under zero
input conditions. In unidirectional applications where measuring very low input currents is desirable, bias the REF
pin to a convenient value above 50 mV to get the output into the linear range of the device. To limit commonmode rejection errors, TI recommends buffering the reference voltage connected to the REF pin.
A less frequently-used output biasing method is to connect the REF pin to the supply voltage, V+. This method
results in the output voltage saturating at 200 mV below the supply voltage when no differential input signal is
present. This method is similar to the output saturated low condition with no input signal when the REF pin is
connected to ground. The output voltage in this configuration only responds to negative currents that develop
negative differential input voltage relative to the device IN– pin. Under these conditions, when the differential
input signal increases negatively, the output voltage moves downward from the saturated supply voltage. The
voltage applied to the REF pin must not exceed the device supply voltage.

9.2.1.3 Application Curve
Output Voltage
(1 V/div)
An example output response of a unidirectional configuration is shown in Figure 31. With the REF pin connected
directly to ground, the output voltage is biased to this zero output level. The output rises above the reference
voltage for positive differential input signals but cannot fall below the reference voltage for negative differential
input signals because of the grounded reference voltage.

9.2.2.1 Design Requirements
The device is a bidirectional, current-sense amplifier capable of measuring currents through a resistive shunt in
two directions. This bidirectional monitoring is common in applications that include charging and discharging
operations where the current flow-through resistor can change directions.
9.2.2.2 Detailed Design Procedure
The ability to measure this current flowing in both directions is enabled by applying a voltage to the REF pin, as
shown in Figure 32. The voltage applied to REF (VREF) sets the output state that corresponds to the zero-input
level state. The output then responds by increasing above VREF for positive differential signals (relative to the IN–
pin) and responds by decreasing below VREF for negative differential signals. This reference voltage applied to
the REF pin can be set anywhere between 0 V to V+. For bidirectional applications, VREF is typically set at midscale for equal signal range in both current directions. In some cases, however, VREF is set at a voltage other
than mid-scale when the bidirectional current and corresponding output signal do not need to be symmetrical.
9.2.2.3 Application Curve
Output Voltage
(1 V/div)
An example output response of a bidirectional configuration is shown in Figure 33. With the REF pin connected
to a reference voltage, 2.5 V in this case, the output voltage is biased upwards by this reference level. The
output rises above the reference voltage for positive differential input signals and falls below the reference
voltage for negative differential input signals.

10 Power Supply Recommendations
The input circuitry of the INA210-INA215 can accurately measure beyond its power-supply voltage, V+. For
example, the V+ power supply can be 5 V, whereas the load power-supply voltage can be as high as 26 V.
However, the output voltage range of the OUT pin is limited by the voltages on the power-supply pin. Note also
that the INA210-INA215 can withstand the full input signal range up to 26 V at the input pins, regardless of
whether the device has power applied or not.
11 Layout
11.1 Layout Guidelines
•
•
Connect the input pins to the sensing resistor using a Kelvin or 4-wire connection. This connection technique
ensures that only the current-sensing resistor impedance is detected between the input pins. Poor routing of
the current-sensing resistor commonly results in additional resistance present between the input pins. Given
the very low ohmic value of the current resistor, any additional high-current carrying impedance can cause
significant measurement errors.
The power-supply bypass capacitor should be placed as closely as possible to the supply and ground pins.
The recommended value of this bypass capacitor is 0.1 μF. Additional decoupling capacitance can be added
to compensate for noisy or high-impedance power supplies.

12.4 Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
