DESCRIPTION The OPA111 is a precision monolithic dielectrically (R) isolated FET (Difet ) operational amplifier. Outstanding performance characteristics allow its use in the most critical instrumentation pplications. 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 patented circuit design techniques. 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.
