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.
