NOTES: (1) Packages must be derated based on _JA = 150/W (P package); _JA = 200/W (M package); _JA = 100/W (U package). (2) Short circuit may be to power supply common only. Rating applies to +25 ambient. Observe dissipation limit and T_J.

The OPA121 is a precision monolithic dielectricallyisolated FET (Difet ^®) operational amplifier. Outstanding 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 OPA121.

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 specifications and reduced susceptibility to flicker noise.

Standard 741 pin configuration allows upgrading of existing designs to higher performance levels.
