OPA111AM Datasheet PDF - Burr Brown

●DESCRIPTION

●The OPA111 is a precision monolithic dielectrically isolated FET (

●Difet

●®) operational amplifier. Outstand ing performance characteristics allow its use in the most critical instrumentation 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 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.
