INA271 - Unidirectional Measurement Current-Shunt Monitor

Download the INA271 datasheet PDF. This datasheet also covers the INA270 variant, as both devices belong to the same unidirectional measurement current-shunt monitor family and are provided as variant models within a single manufacturer datasheet.

Description

The INA270 and INA271 family of voltage-output, current-sense amplifiers can sense drops across shunt resistors at common-mode voltages from

16 V to +80 V, independent of the supply voltage.

The INA270 and INA271 pinouts readily enable filtering.
