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.
