ADAU1966 is a 16-channel high performance differential output, 192 kHz, 24-bit DAC
The ADAU1966 is a single‑chip, 16‑channel digital‑to‑analog converter featuring differential outputs, a built‑in PLL, and low‑EMI design. It operates from 2.5 V digital and 3.3 V or 5 V analog supplies and includes a linear regulator for the digital supply. The device is offered in an 80‑lead LQFP package and is qualified for automotive use.
Key specifications include a dynamic range of 118 dB, total harmonic distortion of –98 dB (typ), and a full‑scale differential output of 3 V rms. Power consumption is 299 mW total at AVDD = 3.3 V. The part supports sample rates from 32 kHz to 192 kHz and provides flexible data formats such as I²S, TDM, and left/right‑justified modes.
