GENERAL DESCRIPTION
The AD8210 is a single-supply, difference amplifier ideal for
amplifying small differential voltages in the presence of large
common-mode voltages. The operating input common-mode
voltage range extends from −2 V to +65 V. The typical supply
voltage is 5 V.
The AD8210 is offered in a SOIC package. The operating
temperature range is −40°C to +125°C.
Excellent ac and dc performance over temperature keep errors
in the measurement loop to a minimum. Offset drift and gain
drift are guaranteed to a maximum of 8 μV/°C and 20 ppm/°C,
respectively.
Rev. D
The output offset can be adjusted from 0.05 V to 4.9 V with
a 5 V supply by using the VREF1 pin and the VREF2 pin. With the
VREF1 pin attached to the V+ pin and the VREF2 pin attached to
the GND pin, the output is set at half scale. Attaching both VREF1
and VREF2 to GND causes the output to be unipolar, starting
near ground. Attaching both VREF1 and VREF2 to V+ causes the
output to be unipolar, starting near V+. Other offsets can be
obtained by applying an external voltage to VREF1 and VREF2.

THEORY OF OPERATION
The differential currents through Q1 and Q2 are converted
into a differential voltage by R3 and R4. A2 is configured as an
instrumentation amplifier. The differential voltage is converted
into a single-ended output voltage by A2. The gain is internally
set with precision-trimmed, thin film resistors to 20 V/V.
In typical applications, the AD8210 amplifies a small differential
input voltage generated by the load current flowing through a
shunt resistor. The AD8210 rejects high common-mode voltages
(up to 65 V) and provides a ground referenced buffered output
that interfaces with an analog-to-digital converter (ADC).
Figure 26 shows a simplified schematic of the AD8210.
The output reference voltage is easily adjusted by the VREF1 pin
and the VREF2 pin. In a typical configuration, VREF1 is connected
to VCC while VREF2 is connected to GND. In this case, the output
is centered at VCC/2 when the input signal is 0 V.
The AD8210 is comprised of two main blocks, a differential
amplifier and an instrumentation amplifier. A load current
flowing through the external shunt resistor produces a voltage
at the input terminals of the AD8210. The input terminals are
connected to the differential amplifier (A1) by R1 and R2. A1
nulls the voltage appearing across its own input terminals by
adjusting the current through R1 and R2 with Q1 and Q2.
When the input signal to the AD8210 is 0 V, the currents in R1
and R2 are equal. When the differential signal is nonzero, the
current increases through one of the resistors and decreases in
the other. The current difference is proportional to the size and
polarity of the input signal.

MODES OF OPERATION
The AD8210 can be adjusted for unidirectional or bidirectional
operation.
UNIDIRECTIONAL OPERATION
Unidirectional operation allows the AD8210 to measure
currents through a resistive shunt in one direction. The basic
modes for unidirectional operation are ground referenced
output mode and V+ referenced output mode.
V+ Referenced Output
This mode is set when both reference pins are tied to the
positive supply. It is typically used when the diagnostic scheme
requires detection of the amplifier and wiring before power is
applied to the load (see Figure 28 and Table 5).
RS
+IN
–IN
In unidirectional operation, the output can be set at the negative
rail (near ground) or at the positive rail (near V+) when the
differential input is 0 V. The output moves to the opposite rail
when a correct polarity differential input voltage is applied. In
this case, full scale is approximately 250 mV. The required
polarity of the differential input depends on the output voltage
setting. If the output is set at ground, the polarity needs to be
positive to move the output up (see Table 5). If the output is set
at the positive rail, the input polarity needs to be negative to
move the output down (see Table 6).

VREF 2
When using the AD8210 in this mode, both reference inputs
are tied to ground, which causes the output to sit at the negative
rail when the differential input voltage is zero (see Figure 27
and Table 4).

Bidirectional operation allows the AD8210 to measure currents
through a resistive shunt in two directions. The output offset
can be set anywhere within the output range. Typically, it is set
at half scale for equal measurement range in both directions. In
some cases, however, it is set at a voltage other than half scale
when the bidirectional current is nonsymmetrical.

External Referenced Output
RS
Tying both VREF pins together to an external reference produces
an output offset at the reference voltage when there is no
differential input (see Figure 29). When the input is negative
relative to the −IN pin, the output moves down from the
reference voltage. When the input is positive relative to the
−IN pin, the output increases.

Splitting an External Reference
In this case, an external reference is divided by two with
an accuracy of approximately 0.2% by connecting one
VREF pin to ground and the other VREF pin to the reference
voltage (see Figure 30).
By tying one reference pin to V+ and the other to the GND pin,
the output is set at midsupply when there is no differential input
(see Figure 31). This mode is beneficial because no external
reference is required to offset the output for bidirectional
current measurement. This creates a midscale offset that is
ratiometric to the supply, meaning that if the supply increases
or decreases, the output still remains at half scale. For example,
if the supply is 5.0 V, the output is at half scale or 2.5 V. If the
supply increases by 10% (to 5.5 V), the output also increases by
10% (2.75 V).
Note that Pin VREF1 and Pin VREF2 are tied to internal precision
resistors that connect to an internal offset node. There is no
operational difference between the pins.
RS

For proper operation, the AD8210 output offset should not be
set with a resistor voltage divider. Any additional external
resistance could create a gain error. A low impedance voltage
source should be used to set the output offset of the AD8210.

INPUT FILTERING
In typical applications, such as motor and solenoid current
sensing, filtering at the input of the AD8210 can be beneficial
in reducing differential noise, as well as transients and current
ripples flowing through the input shunt resistor. An input lowpass filter can be implemented as shown in Figure 32.
Adding outside components, such as RFILTER and CFILTER,
introduces additional errors to the system. To minimize these
errors as much as possible, it is recommended that RFILTER be
10 Ω or lower. By adding the RFILTER in series with the 2 kΩ
internal input resistors of the AD8210, a gain error is
introduced. This can be calculated by

The AD8210 is ideal for high-side or low-side current sensing.
Its accuracy and performance benefits applications, such as
3-phase and H-bridge motor control, solenoid control, and
power supply current monitoring.
For solenoid control, two typical circuit configurations are used:
high-side current sense with a low-side switch, and high-side
current sense with a high-side switch.

Figure 34. High-Side Switch
Using a high-side switch connects the battery voltage to the
load when the switch is closed. This causes the common-mode
voltage to increase to the battery voltage. In this case, when the
switch is opened, the voltage reversal across the inductive load
causes the common-mode voltage to be held one diode drop
below ground by the clamp diode.
Another typical application for the AD8210 is as part of the
control loop in H-bridge motor control. In this case, the AD8210
is placed in the middle of the H-bridge (see Figure 35) so that it
can accurately measure current in both directions by using the
shunt available at the motor. This configuration is beneficial for
measuring the recirculation current to further enhance the
control loop diagnostics.

Figure 33. Low-Side Switch
In this circuit configuration, when the switch is closed, the
common-mode voltage moves down to the negative rail. When
the switch is opened, the voltage reversal across the inductive
load causes the common-mode voltage to be held one diode
drop above the battery by the clamp diode.

HIGH-SIDE CURRENT SENSE WITH A HIGH-SIDE
SWITCH
NC = NO CONNECT
This configuration minimizes the possibility of unexpected
solenoid activation and excessive corrosion (see Figure 34). In
this case, both the switch and the shunt are on the high side.
When the switch is off, the battery is removed from the load,
which prevents damage from potential short circuits to ground,
while still allowing the recirculation current to be measured and
diagnostics to be preformed. Removing the power supply from
the load for the majority of the time minimizes the corrosive
effects that could be caused by the differential voltage between
the load and ground.
Figure 35. Motor Control Application
The AD8210 measures current in both directions as the H-bridge
switches and the motor changes direction. The output of the
AD8210 is configured in an external reference bidirectional
mode (see the Modes of Operation section).

INDUCTIVE
LOAD
In this case, the PWM control switch is ground referenced. An
inductive load (solenoid) is tied to a power supply. A resistive
shunt is placed between the switch and the load (see Figure 33).
An advantage of placing the shunt on the high side is that the
entire current, including the recirculation current, can be measured because the shunt remains in the loop when the switch is
off. In addition, diagnostics can be enhanced because short circuits
to ground can be detected with the shunt on the high side.
