DESCRIPTION
The INA132 is a low power, unity-gain differential
amplifier consisting of a precision op amp with a
precision resistor network. The on-chip resistors are
laser trimmed for accurate gain and high common-
mode rejection. Excellent TCR tracking of the resis-
tors maintains gain accuracy and common-mode re-
jection over temperature. The internal op amp’s com-
mon-mode range extends to the negative supply—
ideal for single-supply applications. It operates on
single (2.7V to 36V) or dual supplies (±1.35V to
±18V).
The differential amplifier is the foundation of many
commonly used circuits. The INA132 provides this
circuit function without using an expensive precision
resistor network. The INA132 is available in 8-pin
DIP and SO-8 surface-mount packages and is speci-
fied for operation over the extended industrial tem-
perature range, –40°C to +85°C.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with ap-
propriate 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.
