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 bandwidth

and low distortion minimize AC errors. All specifications

are rated with a 1kΩ 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.
