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 AD8065 single and AD8066 dual FastFET operational amplifiers. Designed for high-performance industrial and automotive applications, these FET-input amplifiers offer exceptional speed with 145 MHz bandwidth and 180 V/µs slew rate. Key parameters include ultra-low input bias current of 1 pA, low noise of 7 nV/√Hz, and a wide supply range from 5 V to 24 V. The devices support rail-to-rail outputs and operate with only 6.4 mA typical supply current per amplifier. Available in small SOIC-8, MSOP-8, and SOT-23-5 packages, they are ideal for video, filtering, and driver circuits.
