00 — Overview

What the ADA4807 family does

The ADA4807-1, ADA4807-2, and ADA4807-4 are low noise, rail-to-rail input and output operational amplifiers available in single, dual, and quad configurations. These devices feature 3.1 nV/√Hz input voltage noise, 180 MHz bandwidth, 225 V/μs slew rate, and 1.0 mA quiescent current per amplifier. They operate over industrial temperature ranges and are fully specified at 3 V, 5 V, and ±5 V supplies. Engineers typically use them for high resolution ADC drivers, portable battery-powered instruments, high component density data acquisition systems, audio signal conditioning, and active filters where power consumption is critical.
