The AD5025/AD5045/AD5065 are low power, dual 12-/14-/16-bit buffered voltage DACs with various features and functions, suitable for a wide range of applications.
The AD5025/AD5045/AD5065 family are low‑power, dual‑channel nanoDACs offering 12‑, 14‑ or 16‑bit resolution with +1 LSB INL. They operate from a single 4.5 V to 5.5 V supply, feature individual reference pins, rail‑to‑rail outputs, and a high‑speed 3‑wire serial interface compatible with SPI, QSPI and MICROWIRE.
The devices include three selectable power‑down modes, a power‑down lockout pin, and an LDAC function for simultaneous channel updates. Detailed specifications cover static performance, AC characteristics, timing, absolute maximum ratings, and pin functions.
