8.1 Overview

The INA296x is a high-side, inline, or low-side bidirectional, high-speed current-sense amplifier that offers a wide common-mode range, precision zero-drift topology, excellent common-mode rejection ratio (CMRR) and fast slew rate. Different gain versions are available to optimize the output dynamic range based on the application. The INA296x is designed using an architecture that enables low bias currents of 35 µA with a specified common-mode voltage range from –5 V to 110 V with signal bandwidths up to 1.1 MHz.
