The OPA627 is unity-gain stable.
The OPA637 is stable in gains equal to or greater than five.
DESCRIPTION The OPA627 and OPA637 Difet operational amplifiers provide a new level of performance in a precision FET op amp.
When compared to the popular OPA111 op amp, the OPA627/637 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 OPA627/637 is fabricated on a high-speed, dielectrically-isolated complementary NPN/PNP process.
It operates over a wide range of power supply voltage— ±4.
5V to ±18V.
Laser-trimmed Difet input circuitry provides high accuracy and low-noise performance comparable with the best bipolar-input op amps.
Trim 1 Difet fabrication achieves extremely low input bias currents without compromising input voltage noise performance.
Low input bias current is maintained over a wide input common-mode voltage range with unique cascode circuitry.
The OPA627/637 is available in plastic DIP, SOIC and metal TO-99 packages.
Industrial and military temperature range models are available.
