DESCRIPTION
The OPA627 and OPA637 Difet operational amplifi-
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. Laser-trimmed Difet input circuitry
provides high accuracy and low-noise performance
comparable with the best bipolar-input op amps.

OPERATIONAL AMPLIFIERS
APPLICATIONS
5
High frequency complementary transistors allow in-
creased circuit bandwidth, attaining dynamic perform-
ance not possible with previous precision FET op
amps. The OPA627 is unity-gain stable. The OPA637
is stable in gains equal to or greater than five.
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.
