7.1 Overview

The OPA164x-Q1 family of operational amplifiers combine an ultra-low noise JFET input stage with a rail-to-rail output stage to provide high overall performance in audio applications. The internal topology is selected specifically to deliver extremely low distortion, consume limited power, and accommodate small packages. These amplifiers are well-suited for analog signal processing applications such as active filter circuits, pre-amplifiers, and tone controls. The unique input stage design and semiconductor processes used in this device deliver extremely high performance even in applications with high source impedance and wide common-mode voltage swings.
