7.1 Overview

The OPA169x amplifiers are unity-gain stable, dual and quad op amps with low noise. The Functional Block Diagram shows a simplified schematic of the OPA169x (one channel shown). The device consists of a very low noise input stage with a folded cascode and a rail-to-rail output stage. A proprietary distortion reduction technology allows the OPA169x family of amplifiers to achieve significantly lower distortion than other op amps that consume the equal or greater power supply current.
