MAS9560

Stereo Audio Driver DAC

• 16-Bit Stereo Audio DAC

• Stereo Headphone Drivers

• Mono Earpiece Driver

• Mono Loudspeaker Driver

• Mixing of Analog and Digital

Audio Signals

• Integrated LDO

• Flexible Power Down Control

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.
