OPA627AU Description

The OPA627 Difet? operational amplifiers provide a new level of performance in a precision FET operational amplifier. When compared to the popular OPA111 operational amplifier, the OPA627 has lower noise, lower offset voltage, and higher speed. The OPA627 is useful in a broad range of precision and high speed analog circuitry.
The OPA627 is fabricated on a high-speed, dielectrically-isolated complementary NPN/PNP process. It operates over a wide range of power supply voltage of ±4.5 V to ±18 V. Laser-trimmed Difet input circuitry provides high accuracy and low-noise performance comparable with the best bipolar-input operational amplifiers. The OPA627 is unity-gain stable. The OPA637 is stable in gains equal to or greater than five. The OPA627 is available in plastic PDIP, SOIC, and metal TO-99 packages. Industrial and military temperature range models are available.
