6.1 Overview

The INA950-SEP is a high-side only current-sense amplifier that offers a wide common-mode range, precision zero-drift topology, excellent common-mode rejection ratio (CMRR), high bandwidth, and fast slew rate. Different gain versions are available to optimize the output dynamic range based on the application. The INA950-SEP is designed using a transconductance architecture with a current-feedback amplifier that enables low bias currents of 20µA and a common-mode voltage of 80V.
