● HIGH-IMPEDANCE SENSOR AMPS  
● HIGH-PERFORMANCE AUDIO CIRCUITRY  
● OPA627: Unity-Gain Stable  
● OPA637: Stable in Gain ≥ 5  
● 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.  
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 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.  
The OPA627/637 is available in plastic DIP, SOIC  
and metal TO-99 packages. Industrial and military  
temperature range models are available.
