1 Overview

The INA950-SEP is a radiation-tolerant, single channel, ultra-precise, current-sense amplifier that can operate from a single 2.7V to 20V supply and consumes just 370μA. 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 a fast slew rate. 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.

See the INA950-SEP product page on ti.com for more details.
