DESCRIPTION

The MAS9560 Stereo Audio DAC chip is specially intended to audio applications in portable devices. It has both analog and digital inputs for audio data thus enabling the mixing of signals. MAS9560 is equipped with integrated high performance LDO, which ensures high quality of output signal even in noisy power supply environment. MAS9560 has three audio outputs (for headphone, earpiece and loudspeaker) making it an ideal choice for space critical applications. Since current consumption is a critical factor in portable devices, MAS9560 has flexible power down control enabling the shutting down of the parts of the circuit that are not in use.
