The INA2132 is a dual low power, unity-gain differ- ence 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. Ex- cellent TCR tracking of the resistors maintains gain accuracy and common-mode rejection over tempera- ture. The internal op amp’s common-mode range extends to the negative supply—ideal for single-sup- ply 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, –40°C to +85°C. A single version of this product with similar specifi- cations is also available. See the INA132 data sheet for details.
