Five fixed gains are available: 50V/V, 100V/V, 200V/V, 500V/V, or 1000V/V. The low offset of the Zerø-Drift architecture enables current sensing with maximum drops across the shunt as low as 10mV full-scale. These devices operate from a single +2.7V to +26V power supply, drawing a maximum of 100µA of supply current. All versions are specified over the extended operating temperature range (–40°C to +125°C), and offered in an SC70 package.

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 resistance. Reference Voltage Supply RSHUNT Load 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 gain INA213 or INA214 to accommodate larger shunt drops on the upper-end of the scale. For instance, an INA213 operating on a 3.3V supply could easily handle a full-scale shunt drop of 60mV, with only 60µV of offset. UNIDIRECTIONAL OPERATION REF GND INA21x OUT R1 R3 IN- Output +2.7V to +26V V+ CBYPASS 0.01mF to 0.1mF IN+ R2 R4 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. POWER SUPPLY The input circuitry of the INA210-INA214 can accurately measure beyond its power-supply voltage, V+. For example, the V+ power supply can be 5V, whereas the load power supply voltage can be as high as +26V. However, the output voltage range of the OUT terminal is limited by the voltages on the power-supply pin. Note also that the INA210-INA214 can withstand the full –0.3V to +26V in the input pins, regardless of whether the device has power applied or not. Unidirectional operation allows the INA210-INA214 to measure currents through a resistive shunt in one direction. The most frequent case of unidirectional operation sets the output at ground by connecting the REF pin to ground. In unidirectional applications where the highest possible accuracy is desirable at very low inputs, bias the REF pin to a convenient value above 50mV to get the device output swing into the linear range for zero inputs. A less frequent case of unipolar output biasing is to bias the output by connecting the REF pin to the supply; in this case, the quiescent output for zero input is at quiescent supply. This configuration would only respond to negative currents (inverted voltage polarity at the device input). BIDIRECTIONAL OPERATION Bidirectional operation allows the INA210-INA214 to measure currents through a resistive shunt in two directions. In this case, the output can be set anywhere within the limits of what the reference inputs allow (that is, between 0V to V+). Typically, it is set at half-scale for equal range in both directions. In some cases, however, it is set at a voltage other than half-scale when the bidirectional current is nonsymmetrical. The quiescent output voltage is set by applying voltage to the reference input. Under zero differential input conditions the output assumes the same voltage as is applied to the reference input. SELECTING RS The zero-drift offset performance of the INA210-INA214 offers several benefits. Most often, the primary advantage of the low offset characteristic enables lower full-scale drops across the shunt. For example, non-zero-drift current shunt monitors typically require a full-scale range of 100mV. The INA210-INA214 series gives equivalent accuracy at a full-scale range on the order of 10mV. This accuracy reduces shunt dissipation by an order of magnitude with many additional benefits. 8 Submit Documentation Feedback Copyright © 2008, Texas Instruments Incorporated Product Folder Link(s): INA210 INA211 INA212 INA213 INA214 INA210, INA211 INA212, INA213 INA214 www.ti.com ....................................................................................................................................................................................................... SBOS437 – MAY 2008 INPUT FILTERING An obvious and straightforward location for filtering is at the output of the INA210-INA214; however, this location negates the advantage of the low output impedance of the internal buffer. The only other option for filtering is at the input pins of the INA210-INA214; this location requires consideration of the ±30% tolerance of the input impedance. Figure 24 shows a filter placed at the input pins.

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-INA214 in shutdown mode shown in Figure 25.

Input Filter 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 Equation 1: GainError% = 100 - [100 ´ {R/(R + RFILT)}] (1) Where R is the value for R3 or R4 from Table 1 for the model is in question.

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 approximately 2%.

Figure 25. Basic Circuit for Shutting Down INA210-INA214 with Grounded Reference Note that there is typically slightly more than 1MΩ impedance (from the combination of 1MΩ feedback and 5kΩ input resistors) from each input of the INA210-INA214 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 1MΩ impedance from the shunt to ground is straightforward. However, if the reference or op amp is powered while the INA210-INA214 is shut down, the calculation is direct; instead of assuming 1MΩ to ground, however, assume 1MΩ 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 it is unpowered, little or no current flows through the 1MΩ path. Regarding the 1MΩ path to the output pin, the output stage of a disabled INA210-INA214 does constitute a good path to ground; consequently, this current is directly proportional to a shunt common-mode voltage impressed across a 1MΩ resistor.

Below 2V common-mode, the only current effects are the result of the 1MΩ resistors. REF INPUT IMPEDANCE EFFECTS As with any difference amplifier, the INA210-INA214 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-INA214 output can be sensed differentially, such as by a differential input analog-to-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-INA214 by using the REF pin as a reference. Supply RSHUNT Load REF INA21x OUT Output ADC USING THE INA210 WITH COMMON-MODE TRANSIENTS ABOVE 26V With a small amount of additional circuitry, the INA210-INA214 series can be used in circuits subject to transients higher than 26V, 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 shown in Figure 27 as a working impedance for the zener. It is desirable to keep these resistors as small as possible, most often around 10Ω. Larger values can be used with an effect on gain that is discussed in the section on input filtering. Because this circuit is limiting only short-term transients, many applications are satisfied with a 10Ω 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.

SBOS437 – MAY 2008 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-to-back 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.
