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.

ELECTROSTATIC

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.
