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.

NOTES: (1) Sample tested—this parameter is guaranteed. (2) Offset voltage, offset current, and bias current are measured with the units fully warmed up. (3) Overload
recovery is defined as the time required for the output to return from saturation to linear operation following the removal of a 50% input overdrive. (4) Typical θJ-A =
150°C/W for plastic DIP.
