Analog Devices AD1866 Dual 16‑Bit Audio DAC Datasheet
The AD1866 is a complete monolithic dual 16‑bit digital‑to‑analog converter that operates from a single +5 V supply. It integrates CMOS logic, bipolar and MOS linear elements, and laser‑trimmed thin‑film resistors to achieve low THD+N (0.005 % typical), high signal‑to‑noise ratio (95 dB typical) and excellent channel separation (115 dB typical). The device is offered in 16‑pin plastic DIP or SOIC packages and is suitable for multimedia workstations, PC audio add‑in boards, portable CD/DAT players and automotive audio applications.
The datasheet provides detailed electrical specifications, absolute maximum ratings, grounding and power‑supply recommendations, as well as recommended circuit schematics for noise reduction and biasing. Typical performance graphs illustrate THD+N versus frequency, channel separation, and power‑supply rejection, helping designers optimize audio quality in battery‑powered or low‑power systems.
