DESCRIPTION

The OPA124 is a precision monolithic FET opera-

tional amplifier using a Difet (dielectrical isolation)

manufacturing process. Outstanding DC and AC per-

formance characteristics allow its use in the most

critical instrumentation applications.

Noise-Free Cascode⁽²⁾

Bias current, noise, voltage offset, drift, open-loop

gain, common-mode rejection and power supply re-

jection are superior to BIFET and CMOS amplifiers.

Difet fabrication achieves extremely low input bias

currents without compromising input voltage noise

performance. Low input bias current is maintained

over a wide input common-mode voltage range with

unique cascode circuitry. This cascode design also

allows high precision input specifications and reduced

susceptibility to flicker noise. Laser trimming of thin-

film resistors gives very low offset and drift.

OPA124 Simplified Circuit

Compared to the popular OPA111, the OPA124 gives

comparable performance and is available in an 8-pin

PDIP and 8-pin SOIC package.
