DESCRIPTION
The INA213 and INA214 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. The INA213 offers a fixed gain
of 50 V/V, and the INA214 offers a fixed gain of 100 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.
The devices operate from a single 2.7-V to 26-V power supply, drawing a maximum of 100 µA of supply current.
They are specified over the operating temperature range of –40°C to 125°C and are offered in an SC70 package.

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.

APPLICATION INFORMATION
BASIC CONNECTIONS
Figure 23 shows the basic connections of the INA213 or INA214. 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.

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 INA21x 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 terminal is limited by the voltages on the power-supply pin. Note also that the
INA21x can withstand the full –0.3 V to 26 V in the input pins, regardless of whether the device has power
applied or not.
SELECTING RS
The zero-drift offset performance of the INA21x 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 100 mV.
The INA21x 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
gain INA213 or INA214 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 60 µV of
offset.
UNIDIRECTIONAL OPERATION
Unidirectional operation allows the INA21x 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 50 mV 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 INA21x 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 0 V
and 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.
INPUT FILTERING
An obvious and straightforward location for filtering is at the output of the INA21x; 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 INA21x; this location requires consideration of the ±30% tolerance of the input impedance. Figure 24
shows a filter placed at the input pins.

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 in question.

Using an INA212, for example, the total effect on gain error can be calculated by replacing the R with
1 kΩ – 30%, (or 700 Ω) or 1 kΩ + 30% (or 1.3 kΩ). The tolerance extremes of RFILT can also be inserted into the
equation. If a pair of 100-Ω 1% resistors are used on the inputs, the initial gain error is approximately 2%.

SHUTTING DOWN
While the INA21x 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 INA21x 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 INA21x in shutdown mode shown in Figure 25.

NOTE: 1-MW paths from shunt inputs to reference and INA21x outputs.
Figure 25. Basic Circuit for Shutting Down INA21x With 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 INA21x 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 INA21x 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 it is unpowered, 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 INA21x 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
common-mode, the only current effects are the result of the 1-MΩ resistors.
REF INPUT IMPEDANCE EFFECTS
As with any difference amplifier, the INA21x 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 INA21x 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 INA21x by using the REF pin as a
reference.

Figure 26. Sensing INA21x to Cancel Effects of Impedance on the REF Input
USING THE INA21x WITH COMMON-MODE TRANSIENTS ABOVE 26 V
With a small amount of additional circuitry, the INA21x 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 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 10 Ω. 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 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.

SBOS475B –MARCH 2009–REVISED JUNE 2010
If low-power zener diodes 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. In either of these examples, the total
board area required by the INA21x with all protective components is less than that of an SO-8 package, and only
slightly greater than that of an MSOP-8 package.
