open-in-new Find other General-purpose op amps

Description

The OPA602 is a precision, wide bandwidth FET operational amplifier. Monolithic Difet (dielectrically isolated FET) construction provides an unusual combination of high-speed and accuracy.

Its wide-bandwidth design minimizes dynamic errors. High slew rate and fast settling time allow accurate signal processing in pulse and data conversion applications. Wide band-width and low distortion minimize AC errors. All specifications are rated with a 1k resistor in parallel with 500pF load. The OPA602 is unity-gain stable and easily drives capacitive loads up to 1500pF.

Laser-trimmed input circuitry provides offset voltage and drift performance normally associated with precision bipolar op amps. Difet construction achieves extremely low input bias currents (1pA max) without compromising input voltage noise.

The OPA602’s unique input cascode circuitry maintains low input bias current and precise input characteristics over its full input common-mode voltage range.
