opa602 pdf datasheet (High-Spe

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 1kW
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.
