The OPAx323 family of rail-to-rail input and output operational amplifiers is specifically designed for variety of high gain and high speed applications. These devices operate from 1.7V to 5.5V, are unity-gain stable, and are also an excellent choice for a wide range of general-purpose applications. The output stage is capable of driving small resistive loads connected to any point between V+ and V– as long as the device is not forced into short circuit mode. The input common-mode voltage range includes beyond the rail signal swing and allows the OPAx323 series to be used in many single-supply or dual supply configurations.
