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).
