The OPA111 is a precision monolithic dielectricallyisolated FET (Difet ®) operaTIonal amplifier. Outstandingperformance characterisTIcs allow its use in themost criTIcal instrumentaTIon applications.Noise, bias current, voltage offset, drift, open-loopgain, common-mode rejection, and power supply rejectionare superior to BIFET® amplifiers.Very low bias current is obtained by dielectric isolationwith on-chip guarding.Laser trimming of thin-film resistors gives very lowoffset and drift. Extremely low noise is achieved withpatented circuit design techniques. A new cascodedesign allows high precision input specifications andreduced susceptibility to flicker noise.Standard 741 pin configuration allows upgrading ofexisting designs to higher performance levels.
