INA199-Q1 (ACTIVE) AEC-Q100, 26V, Bi-Directional, Zero-Drift, Low-/High-Side, Voltage Output Current Sense Amplifier

 

Description

The INA199-Q1 family is a series of voltage-output, current-sense amplifiers that can sense drops across shunts at common-mode voltages from –0.1 V to 26 V, independent of the supply voltage. Three fixed gains are available: 50 V/V, 100 V/V, and 200 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 from –40°C to +125°C, and are offered in a 6-pin SC70 package.
