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.
