7.1 Overview

The INA293 is a high- or low-side 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 INA293 is designed using a transconductance architecture with a current-feedback amplifier that enables low bias currents of 20 μA with a common-mode voltage of 110 V.
