They are available with three output voltage scales: 20 V/V, 50 V/V, and 100 V/V. The 500-kHz bandwidth simplifies use in current control loops. The INA193A−INA195A devices provide identical functions but alternative pin configurations to the INA196A−INA198A, respectively. The INA193A−INA198A devices operate from a single 2.7-V to 18-V supply, drawing a maximum of 900 μA of supply current. They are specified over the extended operating temperature range (−40°C to 125°C), and are offered in a space-saving SOT-23 package. 8.2 Functional Block Diagram VIN+ VIN R1(1) 5 k: R1(1) 5 k: V+ A1 A2 G = 20, RL = 100 k: G = 50, RL = 250 k: G = 100, RL = 500 k: INA193A-INA198A OUT RL(1) GND 8.3 Feature Description 8.3.1 Basic Connection Figure 20 shows the basic connection of the INA19xA. The input pins, VIN+ and VIN–, should be connected as closely as possible to the shunt resistor to minimize any resistance in series with the shunt resistance. 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.

INA19xA Basic Connections 8.3.2 Selecting RS The value chosen for the shunt resistor, RS, depends on the application and is a compromise between smallsignal accuracy and maximum permissible voltage loss in the measurement line. High values of RS provide better accuracy at lower currents by minimizing the effects of offset, while low values of RS minimize voltage loss in the supply line. For most applications, best performance is attained with an RS value that provides a full-scale shunt voltage range of 50 mV to 100 mV. Maximum input voltage for accurate measurements is 500 mV. 8.3.3 Inside the INA19xA The INA19xA uses a new, unique, internal circuit topology that provides common mode range extending from –16 V to 80 V while operating from a single power supply. The common mode rejection in a classic instrumentation amplifier approach is limited by the requirement for accurate resistor matching. By converting the induced input voltage to a current, the INA19xA provides common mode rejection that is no longer a function of closely matched resistor values, providing the enhanced performance necessary for such a wide common mode range. A simplified diagram (see Figure 20) shows the basic circuit function. When the common mode voltage is positive, amplifier A2 is active. The differential input voltage, VIN+ – VIN– applied across RS, is converted to a current through a 5-kΩ resistor. This current is converted back to a voltage through RL, and then amplified by the output buffer amplifier. When the common mode voltage is negative, amplifier A1 is active. The differential input voltage, VIN+ – VIN– applied across RS, is converted to a current through a 5-kΩ resistor. This current is sourced from a precision current mirror whose output is directed into RL, converting the signal back into a voltage and amplified by the output buffer amplifier. Patent-pending circuit architecture ensures smooth device operation, even during the transition period where both amplifiers A1 and A2 are active. 12 Submit Documentation Feedback Copyright © 2006–2015, Texas Instruments Incorporated Product Folder Links: INA193A-Q1 INA194A-Q1 INA195A-Q1 INA196A-Q1 INA197A-Q1 INA198A-Q1 INA193A-Q1, INA194A-Q1, INA195A-Q1 INA196A-Q1, INA197A-Q1, INA198A-Q1 www.ti.com SBOS366D – AUGUST 2006 – REVISED JULY 2015 Feature Description (continued) RSHUNT LOAD 12 V I1 5V VIN+ 5 kΩ VIN– V+ 5 kΩ V+ INA193A–INA198A OUT for 12-V common mode INA193A–INA198A 5 kΩ GND 5 kΩ OUT for –12-V common mode VIN+ VIN– GND RSHUNT –12 V LOAD I2 Figure 21.

For example, the V+ power supply can be 5 V, whereas the load power-supply voltage is up to 80 V. The output voltage range of the OUT terminal, however, is limited by the voltages on the power-supply pin.

The only other option for filtering is at the input pins of the INA19xA, which is complicated by the internal 5-kΩ ± 30% input impedance (see Figure 25). Using the lowest possible resistor values minimizes both the initial shift in gain and effects of tolerance. The effect on initial gain is given by: 5 kΩ Gain Error % = 100 – ( 100 × ( 5 kΩ + RFILT (1) Total effect on gain error can be calculated by replacing the 5-kΩ term with 5 kΩ – 30% (or 3.5 kΩ) or 5 kΩ + 30% (or 6.5 kΩ). The tolerance extremes of RFILT can also be inserted into the equation. If a pair of 100Ω 1% resistors are used on the inputs, the initial gain error is 1.96%. Worst-case tolerance conditions always occur at the lower excursion of the internal 5-kΩ resistor (3.5 kΩ), and the higher excursion of RFILT, 3% in this case. The specified accuracy of the INA19xA must then be combined in addition to these tolerances. While this discussion treats accuracy worst-case conditions by combining the extremes of the resistor values, it is appropriate to use geometric mean or root sum square calculations to total the effects of accuracy variations.

Input Filter (Gain Error = 1.5% to –2.2%) 8.4.2 Accuracy Variations as a Result Of VSENSE and Common Mode Voltage The accuracy of the INA19xA-Q1 current shunt monitors is a function of two main variables: VSENSE (VIN+ – VIN–) and common mode voltage, VCM, relative to the supply voltage, VS. VCM is expressed as (VIN+ + VIN–)/2; however, in practice, VCM is seen as the voltage at VIN+ because the voltage drop across VSENSE is usually small. 16 Submit Documentation Feedback Copyright © 2006–2015, Texas Instruments Incorporated Product Folder Links: INA193A-Q1 INA194A-Q1 INA195A-Q1 INA196A-Q1 INA197A-Q1 INA198A-Q1 INA193A-Q1, INA194A-Q1, INA195A-Q1 INA196A-Q1, INA197A-Q1, INA198A-Q1 www.ti.com SBOS366D – AUGUST 2006 – REVISED JULY 2015 Device Functional Modes (continued) This section addresses the accuracy of these specific operating regions: Normal Case 1: VSENSE ≥ 20 mV, VCM ≥ VS Normal Case 2: VSENSE ≥ 20 mV, VCM < VS Low VSENSE Case 1: VSENSE < 20 mV, –16 V ≤ VCM < 0 Low VSENSE Case 2: VSENSE < 20 mV, 0 V ≤ VCM ≤ VS Low VSENSE Case 3: VSENSE < 20 mV, VS < VCM ≤ 80 V 8.4.2.1 Normal Case 1: VSENSE ≥ 20 mV, VCM ≥ VS This region of operation provides the highest accuracy. Here, the input offset voltage is characterized and measured using a two-step method. First, the gain is determined by (Equation 2). V - VOUT2 G = OUT1 100 mV - 20 mV where • • VOUT1 = Output voltage with VSENSE = 100 mV VOUT2 = Output voltage with VSENSE = 20 mV (2) The offset voltage is then measured at VSENSE = 100 mV and referred to the input (RTI) of the current shunt monitor, as shown in (Equation 3). æ VOUT1 ö VOSRTI (Referred- To - Input) = ç ÷ - 100 mV è G ø (3) In the Typical Characteristics, the Output Error vs Common Mode Voltage curve shows the highest accuracy for the this region of operation. In this plot, VS = 12 V; for VCM ≥ 12 V, the output error is at its minimum. This case is also used to create the VSENSE ≥ 20 mV output specifications in the Electrical Characteristics table. 8.4.2.2 Normal Case 2: VSENSE ≥ 20 mV, VCM < VS This region of operation has slightly less accuracy than Normal Case 1 as a result of the common mode operating area in which the part functions, as seen in Figure 6. As noted, for this graph VS = 12 V; for VCM < 12 V, the Output Error increases as VCM becomes less than 12 V, with a typical maximum error of 0.005% at the most negative VCM = –16 V. 8.4.2.3 Low VSENSE Case 1: VSENSE < 20 mV, –16 V ≤ VCM < 0; and Low VSENSE Case 3: VSENSE < 20 mV, VS < VCM ≤ 80 V Although the INA19xA-Q1 family of devices are not designed for accurate operation in either of these regions, some applications are exposed to these conditions; for example, when monitoring power supplies that are switched on and off while VS is still applied to the INA19xA-Q1. It is important to know what the behavior of the devices will be in these regions. As VSENSE approaches 0 mV, in these VCM regions, the device output accuracy degrades. A larger-than-normal offset can appear at the current shunt monitor output with a typical maximum value of VOUT = 300 mV for VSENSE = 0 mV. As VSENSE approaches 20 mV, VOUT returns to the expected output value with accuracy as specified in Electrical Characteristics. Figure 26 illustrates this effect using the INA195A and INA198A (Gain = 100).

To achieve the wide input common mode voltage range, these devices use two operational amplifier front ends in parallel. One operational amplifier front end operates in the positive input common mode voltage range, and the other in the negative input region. For this case, neither of these two internal amplifiers dominates and overall loop gain is very low. Within this region, VOUT approaches voltages close to linear operation levels for Normal Case 2. This deviation from linear operation becomes greatest the closer VSENSE approaches 0 V. Within this region, as VSENSE approaches 20 mV, device operation is closer to that described by Normal Case 2. Figure 27 illustrates this behavior for the INA195A. The VOUT maximum peak for this case is tested by maintaining a constant VS, setting VSENSE = 0 mV and sweeping VCM from 0 V to VS. The exact VCM at which VOUT peaks during this test varies from part to part, but the VOUT maximum peak is tested to be less than the specified VOUT tested limit. 2.4 INA195, INA198 VOUT Tested Limit(1) VCM1 2.2 2.0 Ideal 1.8 VCM2 VOUT (V) 1.6 1.4 VCM3 1.2 1.0 VCM4 0.8 0.6 0.4 0.2 0 0 2 4 6 8 10 12 14 16 18 20 22 24 VSENSE (mV) (1) INA193, INA196 VOUT Tested Limit = 0.4 V INA194, INA197 VOUT Tested Limit = 1 V NOTE: VOUT tested limit at VSENSE = 0 mV, 0 ≤ VCM1 ≤ VS.

Use a totem pole output buffer or gate that can provide sufficient drive along with 0.1 μF bypass capacitor, preferably ceramic with good high frequency characteristics. This gate should have a supply voltage of 3 V or greater because the INA19xA-Q1 requires a minimum supply greater than 2.7 V. In addition to eliminating quiescent current, this gate also turns off the 10 μA bias current present at each of the inputs. An example shutdown circuit is shown in Figure 28.

INA19xA-Q1 Example Shutdown Circuit 8.4.4 Transient Protection The –16-V to 80-V common mode range of the INA19xA is ideal for withstanding automotive fault conditions ranging from 12-V battery reversal up to 80-V transients, because no additional protective components are needed up to those levels. In the event that the INA19xA is exposed to transients on the inputs in excess of its ratings, then external transient absorption with semiconductor transient absorbers (zeners or Transzorbs) are necessary. TI does not recommend using MOVs or VDRs except when they are used in addition to a semiconductor transient absorber. Select the transient absorber such that it never allows the INA19xA to be exposed to transients greater than 80 V (that is, allow for transient absorber tolerance, as well as additional voltage due to transient absorber dynamic impedance). Despite the use of internal zener-type ESD protection, the INA19xA does not lend itself to using external resistors in series with the inputs because the internal gain resistors can vary up to ±30%. (If gain accuracy is not important, then resistors can be added in series with the INA19xA inputs with two equal resistors on each input.) 8.4.5 Output Voltage Range The output of the INA19xA is accurate within the output voltage swing range set by the power supply pin, V+. This is best illustrated when using the INA195A or INA198A (which are both versions using a gain of 100), where a 100-mV full-scale input from the shunt resistor requires an output voltage swing of 10 V, and a power-supply voltage sufficient to achieve 10 V on the output.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information The INA193A-INA198A devices measure the voltage developed across a current-sensing resistor when current passes through it. The ability to have shunt common mode voltages from −16-V to 80-V drive and control the output signal with Vs offers multiple configurations, as discussed throughout this section. 9.2 Typical Application The device is a unidirectional, current-sense amplifier capable of measuring currents through a resistive shunt with shunt common mode voltages from −16 V to 80 V. Two devices can be configured for bidirectional monitoring and is common in applications that include charging and discharging operations where the current flow-through resistor can change directions.

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 from 0 V to V+. For bidirectional applications, VREF is typically set at mid- scale 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 are not required to be symmetrical. 9.2.3 Application Curve An example output response of a bidirectional configuration is shown in Figure 30. 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 I_in VOUT Current (I), Voltage (V) 7.5 5 2.5 0 -2.5 -5 -7.5 -10 0 2 4 6 8 10 12 14 16 18 20 Time (µs) Figure 30.

For example, the V+ power supply can be 5 V, whereas the load power-supply voltage is up to 80 V. The output voltage range of the OUT terminal, however, is limited by the voltages on the power-supply pin.

Keep traces short and, when possible, use a printedcircuit-board (PCB) ground plane with surface-mount components placed as close to the device pins as possible. Small ceramic capacitors placed directly across amplifier inputs can reduce RFI/EMI sensitivity. PCB layout should locate the amplifier as far away as possible from RFI sources. Sources can include other components in the same system as the amplifier itself, such as inductors (particularly switched inductors handling a lot of current and at high frequencies). RFI can generally be identified as a variation in offset voltage or dc signal levels with changes in the interfering RF signal. If the amplifier cannot be located away from sources of radiation, shielding may be needed. Twisting wire input leads makes them more resistant to RF fields. The difference in input pin location of the INA193A–INA195A versus the INA196A–INA198A may provide different EMI performance. 11.2 Layout Example Via to Power or Ground Plane Via to Internal Layer Supply Bypass Capacitor Supply Voltage Output Signal OUT V+ GND IN+ IN- Shunt Resistor Figure 31.
