DESCRIPTION
The OPA2111 is a high precision monolithic
dielectrically isolated FET (
Difet
) operational ampli-
fier. Outstanding 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 cascode design
allows high precision input specifications and reduced
susceptibility to flicker noise.
Standard dual op amp pin configuration allows up-
grading of existing designs to higher performance
levels.
