DESCRIPTION

• Choice of Gain

The INA212-Q1, INA213A-Q1, and INA214-Q1

– INA212-Q1: 1000 V/V

devices are voltage-output current-shunt monitors

– INA213A-Q1: 50 V/V

that can sense drops across shunts at common-mode

– INA214-Q1: 100 V/V

voltages from –0.3 V to 26 V, independent of the

supply voltage. The INA212-Q1 offers a fixed gain of

• Quiescent Current: 100 µA (Max)

1000 V/V, INA213A-Q1 offers a fixed gain of 50 V/V,

• SC70 Package

and the INA214-Q1 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.

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.

INA212-Q1, INA213A-Q1 INA214-Q1 www.ti.com SBOS475D – MARCH 2009 – REVISED OCTOBER 2013 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).

However, in current shunt monitoring applications. there is also a concern for how much current is drained from the shunt circuit in shutdown conditions.

INA212-Q1, INA213A-Q1 INA214-Q1 SBOS475D – MARCH 2009 – REVISED OCTOBER 2013 www.ti.com 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.
