AD5623R/AD5643R/AD5663R is a dual 12-/14-/16-bit nanoDAC® with 5 ppm/°C on-chip reference. It features low power, smallest pin-compatible design, user-selectable external or internal reference, guaranteed monotonicity, and other characteristics.
The AD5623R/AD5643R/AD5663R family are low‑power, dual 12‑, 14‑, and 16‑bit buffered voltage‑output DACs that operate from a single 2.7 V to 5.5 V supply. They include an on‑chip 1.25 V or 2.5 V reference with 5 ppm/°C accuracy and offer both internal and external reference options. Power‑down mode reduces current consumption to 480 nA at 5 V, and the devices guarantee monotonic behavior by design.
The parts use a versatile 3‑wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards, supporting clock rates up to 50 MHz. Available in 10‑lead MSOP and 3 mm × 3 mm LFCSP packages, they are suited for portable, battery‑operated instruments, data‑acquisition systems, and programmable voltage sources.
