Low-Cost Stereo Audio DAC

Please check latest availability status for a specific part variant.


The MAX5556 stereo audio sigma-delta digital-to-analog converter (DAC) offers a simple and complete stereo digital-to-analog solution for media servers, set-top boxes, video-game hardware, and other general consumer audio applications. This DAC features built-in digital interpolation/filtering, sigma-delta digital-to-analog conversion, and analog output filtering. Control logic and mute circuitry minimize audible pops and clicks during power-up, power-down, clock changes, or when invalid clock conditions occur.

The MAX5556 receives input data over a 3-wire I2S-compatible interface with left-justified audio data. Data can be clocked by either an external or internal serial clock. The internal serial clock frequency is programmable by selection of a master clock (MCLK) and sample clock (LRCLK) ratio. Sampling rates from 2kHz to 50kHz are supported.

The MAX5556 operates from a single +4.75V to +5.5V analog supply with total harmonic distortion plus noise below -87dB. This device is available in an 8-pin SO package and is specified over the -40°C to +85°C industrial temperature range.
