DESCRIPTION
The OPA602 is a precision, wide bandwidth FET operational
amplifier. Monolithic
Difet (dielectrically isolated FET) con-
struction 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 process-
ing in pulse and data conversion applications. Wide band-
width 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.
