00 — Overview

What the RS855 family does

The RS8551, RS8552, RS8553, and RS8554 are zero-drift, rail-to-rail I/O CMOS operational amplifiers spanning single, dual, and quad configurations. These devices feature a 4.5 MHz gain bandwidth product, 2.7 V/μs slew rate, 130 dB CMRR, and 640 μA per amplifier power consumption. They operate on single or dual supplies from 2.7 V to 5.5 V across an industrial temperature range of -40°C to +125°C. Engineers typically use these amplifiers in temperature sensors, medical instrumentation, pressure sensing, battery-powered devices, and active filtering applications.
