Micro Analog Systems’ Output Power Audio Driver features an integrated high performance LDO

The MAS9560 16-bit Stereo Audio DAC chip is specially designed for portable audio applications. It has both analogue and digital inputs for audio data, thus enabling the easy mixing of signals. MAS9560 is equipped with an integrated high performance LDO, which ensures high quality of output signal even in noisy power supply environment. The circuit has three audio outputs: headphone (80 mW), earpiece (300 mW) and loudspeaker (1100 mW). Since current consumption is a critical factor in portable devices, the MAS9560 has flexible power down control enabling the shutting down of the blocks that are not in use. It has many user selectable options that can be controlled by on-chip registers. The registers can be programmed via I2C or SPI interface protocols. 3-wire serial I2S bus is used for digital audio data transmission for DACs. The chip is available in a 6 x 6, 40-pin QFN package making it an ideal choice for space critical applications. Samples are available now. Price for 10000 pcs is 3.14 Euro each, Ex works.
