The INA132UA is a precision 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 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 dual supplies ±1.35 to ±18V. The differential amplifier is the foundation of many commonly used circuits. The low power single supply INA132 provides this circuit function without using an expensive precision resistor network.
