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.
