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 re-
jection are superior to BIFET
amplifiers.
Very low bias current is obtained by dielectric isola-
tion 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.
