The INA2132 is a dual low power, unity-gain difference amplifier offering excellent value at very low cost. Each channel consists of a precision op amp with a laser-trimmed precision resistor network, providing 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. The difference amplifier is the foundation of many commonly used circuits. The INA2132 provides this circuit function without using an expensive precision resistor network. The INA2132 is available in the SO-14 surface-mount package and is specified for operation over the extended industrial temperature range, 40C to +85C.
