00 — Overview

What the BA10324 does

The BA10358xx, BA2904xx, and BA2902xx families are ground sense operational amplifiers available in dual and quad configurations. These devices operate on a single supply from 3.0V to 36.0V across commercial, industrial, and military temperature ranges. Key specifications include a maximum input offset voltage of 7mV, typical input bias currents of 20nA, and output currents up to 35mA per channel. Engineers typically use these amplifiers for current sensing, buffering, and active filter applications in consumer electronics and industrial systems.
