OPA627 概述

The OPA627 Difet operational amplifiers provide a new level of performance in a precision FET op amp. When compared to the popular OPA111 op amp, the OPA627 has lower noise, lower offset voltage, and much higher speed. It is useful in a broad range of precision and high speed analog circuitry.

The OPA627 is available in plastic DIP, SOIC and metal TO-99 packages. Industrial and military temperature range models are available.
