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. Thi...
