The MAX5556 is a low-cost stereo audio sigma-delta digital-to-analog converter (DAC) that provides 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. It features built-in digital interpolation/filtering, sigma-delta digital-to-analog conversion, and analog output filtering. The MAX5556 receives input data over a 3-wire I2S-compatible interface with left-justified audio data. Sampling rates from 2kHz to 50kHz are supported. The device operates from a single +4.75V to +5.5V analog supply with total harmonic distortion plus noise below -87dB.
The MAX5556 is a low‑cost stereo audio sigma‑delta DAC that offers a complete digital‑to‑analog solution for consumer audio applications such as media servers, set‑top boxes, video‑game hardware, and automotive rear‑seat entertainment. It features built‑in digital interpolation, sigma‑delta conversion, analog output filtering, and click‑less mute circuitry.
The device operates from a single +4.75 V to +5.5 V supply, supports sample rates from 2 kHz to 50 kHz, and provides a 3.5 Vp‑p output swing with +87 dB dynamic range. It is supplied in an 8‑pin SO package and can drive loads of at least 3 kΩ and up to 100 pF capacitance.
