The OPAx323 delivers a robust output drive capability. An output stage with common-source transistors is used to achieve full rail-to-rail output swing capability. The device is designed to have a minimum output short circuit current of ±80mA, making the device an excellent choice for audio driver applications at room temperature and at 5.5V. For resistive loads up to 2kΩ and a power supply of 5.5V, the output swings within a maximum of 55mV to either supply rail, thereby using almost the entire input range of an ADC in ADC driver applications.
