The document describes a dual 16-bit nanoDAC product called AD5663. It has a power supply range of 2.7V to 5.5V, operating current of 250μA, and Rail-to-Rail output capability. The product is suitable for applications such as process control, data acquisition systems, portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, and programmable attenuators.
The AD5663 is a dual 16‑bit buffered voltage‑output DAC that operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design. It offers low power consumption (1.25 mW at 5 V) and a rail‑to‑rail output swing, making it suitable for portable, battery‑operated instruments.
The device provides a versatile 3‑wire serial interface compatible with SPI, QSPI, Microwire and DSP standards, and includes per‑channel power‑down, hardware LDAC and CLR functions. Detailed specifications cover resolution, accuracy, timing, AC characteristics, absolute maximum ratings and pin functions.
