ers 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, dielec-
trically-isolated complementary NPN/PNP process. It
operates over a wide range of power supply voltage—
±4.5V
to
±18V.

provides high accuracy and low-noise performance
comparable with the best bipolar-input op amps.

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.
