DESCRIPTION
The OPA27 and OPA37 are ultra-low noise, high-precision
monolithic operational amplifiers.
Laser-trimmed thin-film resistors provide excellent long-term
voltage offset stability and allow superior voltage offset
compared to common zener-zap techniques.
A unique bias current cancellation circuit allows bias and
offset current specifications to be met over the full –55°C to
+125°C temperature range.
The OPA27 is internally compensated for unity-gain stability.
The decompensated OPA37 requires a closed-loop gain
≥
5.
The Texas Instrument OPA27 and OPA37 are improved
replacements for the industry-standard OP-27 and OP-37.

Exposure to absolute maximum conditions for extended periods may degrade
device reliability. (2) Maximum package power dissipation versus ambient
temperature. (2) To common with

= 15V. (4) The inputs are protected by
back-to-back diodes. Current limiting resistors are not used in order to achieve
low noise. If differential input voltage exceeds
±0.7V,
the input current should
be limited to 25mA.
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments 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 degradation
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.

NOTES: (1) Measured with industry-standard noise test circuit (Figures 1 and 2). Due to errors introduced by this method, these current noise specifications should
be used for comparison purposes only. (2) Offset voltage specification are measured with automatic test equipment after approximately 0.5 seconds from power turn-
on. (3) Unnulled or nulled with 8kΩ to 20kΩ potentiometer. (4) Long-term voltage offset vs time trend line does not include warm-up drift. (5) Typical specification only
on plastic package units. Slew rate varies on all units due to differing test methods. Minimum specification applies to open-loop test. (6) This parameter specified by
design.
