The CXAR41283 stereo headphone driver is designed for portable equipment where board space is limited. The CXAR41283 uses the dual external power supplies PVDD/NVDD to produce a ground-reference output, eliminating the need for large DC-blocking capacitors, saving cost, board space, and component height. The GCXAR41283is a dual channel, low voltage, low power, and high performance amplifiers, which can deliver up to 70mW per channel into a 16Ω load with small THD+N performance. The CXAR41283operates from a dual ±1.8V to ±3.6V supplies, consumes only 7mA of supply current. With excellent AC performance (small THD), it can be designed into a wide range of headphone driving application.
