DESCRIPTION
The OPA124 is a precision monolithic FET opera-
tional amplifier using a Difet (dielectrical isolation)
manufacturing process. Outstanding DC and AC per-
formance characteristics allow its use in the most
critical instrumentation applications.
Bias current, noise, voltage offset, drift, open-loop
gain, common-mode rejection and power supply re-
jection are superior to BIFET and CMOS amplifiers.
Difet fabrication achieves extremely low input bias
currents without compromising input voltage noise
performance. Low input bias current is maintained
over a wide input common-mode voltage range with
unique cascode circuitry. This cascode design also
allows high precision input specifications and reduced
susceptibility to flicker noise. Laser trimming of thin-
film resistors gives very low offset and drift.
Compared to the popular OPA111, the OPA124 gives
comparable performance and is available in an 8-pin
PDIP and 8-pin SOIC package.

NOTES: (1) Offset voltage, offset current, and bias current are measured with the units fully warmed up. For performance at other temperatures see Typical Performance
Curves. (2) 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.
(3) For performance at other temperatures see Typical Performance Curves. (4) Sample tested, 98% confidence. (5) Guaranteed by design.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
The information provided herein is believed to be reliable; however, BURR-BROWN assumes no responsibility for inaccuracies or omissions. BURR-BROWN assumes
no responsibility for the use of this information, and all use of such information shall be entirely at the user’s own risk. Prices and specifications are subject to change
without notice. No patent rights or licenses to any of the circuits described herein are implied or granted to any third party. BURR-BROWN does not authorize or warrant
any BURR-BROWN product for use in life support devices and/or systems.
