3 Description

The INA21x-Q1 family of devices is a voltage-output,

current-shunt monitor (also called a current-sense

amplifier) that can sense drops across shunts at

common-mode voltages from –0.3 V to 26 V,

independent of the supply voltage. Five fixed gains

are available: 50 V/V, 75 V/V, 100 V/V, 200 V/V,

500 V/V, and 1000 V/V. This family of devices is

commonly used for overcurrent detection, voltage

feedback control loops, or as a power monitor. 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. The devices are specified over the

operating temperature range of –40°C to +125°C and

are offered in a 6-pin SC70 package.
