Analog Devices AD5686R/AD5685R/AD5684R Four-Channel nanoDAC+ Datasheet
The AD5686R, AD5685R, and AD5684R belong to the nanoDAC+® family of low‑power, four‑channel buffered voltage output DACs. They provide 16‑, 14‑, or 12‑bit resolution, an internal 2.5 V, 2 ppm/°C reference, and a 1.8 V‑compatible SPI interface that can run up to 50 MHz.
Typical applications include optical transceivers, base‑station power amplifiers, PLC I/O cards, industrial automation, and data‑acquisition systems. The devices are offered in ultra‑compact 3 mm × 3 mm 16‑pin LFCSP and 16‑pin TSSOP packages. This manual is written in Chinese.
