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 commonmode
rejection. Excellent TCR tracking of the resistors
maintains gain accuracy and common-mode rejection
over temperature. The internal op amp’s common-
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 specified
for operation over the extended industrial temperature
range, –40°C to +85°C.
