Dual 8-/10-/12-Bit, High Bandwidth, Multiplying DACs with Serial Interface
The AD5429/AD5439/AD5449 family are CMOS dual‑channel current‑output DACs that operate from a 2.5 V to 5.5 V supply, making them suitable for portable, battery‑powered applications. They provide a 10 MHz multiplying bandwidth, 2.47 MSPS update rate, and support daisy‑chain operation via a serial data out pin.
These devices feature a 3‑wire serial interface compatible with SPI, QSPI, Microwire and most DSP standards. They include built‑in reference input (+10 V), power‑on reset, guaranteed monotonicity, and read‑back capability. Detailed specifications cover resolution, accuracy, timing, absolute maximum ratings, pin functions, and typical performance characteristics.
