00 — Overview

What the AD8065 does

The AD8065/AD8066 are high performance, high speed FET input amplifiers available as single or dual configurations in SOIC-8, MSOP-8, and SOT-23-5 packages. These devices feature a 145 MHz bandwidth, 180 V/µs slew rate, 7 nV/√Hz noise density, and 6.4 mA typical supply current per amplifier. They operate over a wide 5 V to 24 V range with rail-to-rail outputs. The parts are ideal for automotive driver assistance, photodiode preamps, filters, A/D drivers, and video applications requiring low noise and excellent distortion specifications.
