3 Description

The INA210, INA211, INA212, INA213, INA214, and

INA215 are voltage-output, current-shunt monitors

(also

called

current-sense

amplifiers)

that

are

commonly used for overcurrent protection, precision-

current measurement for system optimization, or in

closed-loop feedback circuits. This series of devices

can sense drops across shunts at common-mode

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

supply voltage. Six fixed gains are available: 50 V/V,

75 V/V, 100 V/V, 200 V/V, 500 V/V, or 1000 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.

These devices operate from a single 2.7-V to 26-V

power supply, drawing a maximum of 100 µA of

supply current. All versions are specified over the

extended operating temperature range (–40°C to

125°C), and offered in SC70 and UQFN packages.
