ANALOG DEVICES SigmaDSP 28-/56-Bit Audio Processor with Two ADCs Four DACs ADAU1702 handbook
The ADAU1702 is a single‑chip SigmaDSP audio processor that provides 28‑/56‑bit digital audio processing, two high‑performance ADCs and four DACs, and a built‑in microcontroller‑like control interface. It supports sampling rates up to 192 kHz and offers programmable signal‑processing blocks such as equalizers, dynamics processors, and speaker compensation.
The handbook covers the device’s features, applications, functional block diagram, detailed specifications, pin configurations, power and clock circuitry, digital timing diagrams, register maps, and programming procedures. It also includes mechanical dimensions, ordering information, and regulatory notes.
