MAX5556

The MAX5556MAX5559 stereo audio sigma-delta digital-to-analog converters (DACs) offer a simple and complete stereo digital-to-analog solution for media servers, set-top boxes, video-game hardware, automotive rear-seat entertainment and other general consumer audio applications. These MAX5556 feature 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 MAX5556MAX5559 receive input data over a flexible 3-wire interface, supporting I2S-compatible, left-justified, right-justified 16-bit, and right-justified 18-bit 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 MAX5556MAX5559 operate from a single +4.75V to +5.5V analog supply with total harmonic distortion plus noise below -87dB. These devices are available in 8-pin SO packages and are specified over the -40°C to +85°C industrial temperature range.
