Product Introduction

Overview

The OPA627AUE4, produced by Texas Instruments, is a precision high-speed JFET operational amplifier. It is part of the OPA6x7 series, which includes the OPA627 and OPA637 models. These operational amplifiers are designed to provide superior performance in precision and high-speed analog circuitry. Compared to other op amps like the OPA111, the OPA627 offers lower noise, lower offset voltage, and higher speed. The device is fabricated on a high-speed, dielectrically-isolated, complementary NPN/PNP process and operates over a wide power-supply voltage range of ±4.5V to ±18V.
