DESCRIPTION
The OPA121 is a precision monolithic dielectrically-
isolated FET (
Difet
) operational amplifier. Out-
standing performance characteristics are now
available for low-cost applications.
Noise, bias current, voltage offset, drift, open-loop
gain, common-mode rejection, and power supply
rejection are superior to BIFET
amplifiers.
Very low bias current is obtained by dielectric
isolation with on-chip guarding.
Laser-trimming of thin-film resistors gives very low
offset and drift. Extremely low noise is achieved with
new circuit design techniques (patented). A new
cascode design allows high precision input specifica-
tions and reduced susceptibility to flicker noise.
Standard 741 pin configuration allows upgrading of
existing designs to higher performance levels.
