ACTIVE FILTERS
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.
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鈥?/div>

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.
