DESCRIPTION
+VS
The OPA602 is a precision, wide bandwidth FET
operational amplifier. Monolithic Difet (dielectrically
isolated FET) construction provides an unusual com-
bination 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 appli-
cations. 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 preci-
sion 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 main-
tains low input bias current and precise input charac-
teristics over its full input common-mode voltage
range.
