This document describes the features and characteristics of the OP295/OP495 dual/quad rail-to-rail operational amplifiers. These amplifiers have single-supply operation, rail-to-rail output swing, low offset voltage, high gain bandwidth product, high open-loop gain, unity-gain stability, and low supply current. They are suitable for applications such as battery-operated instrumentation, servo amplifiers, actuator drives, sensor conditioners, and power supply control.
