The OPA2111 is a high precision monolithicdielectrically isolated FET (Difet ) operaTIonal amplifier.Outstanding performance characterisTIcs allow itsuse in the most 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 cascode designallows high precision input specifications and reducedsusceptibility to flicker noise.Standard dual op amp pin configuration allows upgradingof existing designs to higher performancelevels.
