Dual low power, unity-gain difference amplifier, INA2132UA/2K5, Texas Instruments

The INA2132UA/2K5 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 resistor 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 application. The difference amplifier is the foundation of many commonly used circuits. The INA2132UA/2K5 provides this circuit function without using an expensive precision resistor network.
