APPLICATIONS

● PRECISION INSTRUMENTATION

FEATURES

● VERY LOW NOISE: 4.5nV/√Hz at 10kHz

● FAST DATA ACQUISITION

● FAST SETTLING TIME:

OPA627—550ns to 0.01%

OPA637—450ns to 0.01%

● DAC OUTPUT AMPLIFIER

● OPTOELECTRONICS

● LOW V_OS: 100µV max

● SONAR, ULTRASOUND

● LOW DRIFT: 0.8µV/°C max

● LOW I_B: 5pA max

● 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.
