Key datasheet specifications and the closest alternatives, ranked by parametric similarity and grounded in the manufacturer datasheet.

01 — Overview

This Analog Devices datasheet covers the ADA4807-1, -2, and -4 families of low noise, rail-to-rail input/output amplifiers. The document provides electrical specifications, pin configurations, and application guidelines for these high-speed, precision devices available in various packages like SC70, MSOP, LFCSP, and TSSOP. Key performance parameters include 3.1 nV/√Hz input noise at 100 kHz, 180 MHz bandwidth, a 225 V/μs slew rate, and only 1.0 mA quiescent supply current per amplifier. These amplifiers are fully specified across +3 V, +5 V, and ±5 V supplies, making them ideal for driving high-resolution ADCs, portable instruments, audio conditioning, and active filters while maintaining excellent DC precision and low distortion.
