Overview
The AD5662ARJZ-1500RL7, produced by Analog Devices Inc., is a member of the nanoDAC family. It is a low power, single, 16-bit buffered voltage-out Digital-to-Analog Converter (DAC) that operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design. This DAC requires an external reference voltage to set the output range and features a power-on reset circuit that ensures the DAC output powers up to 0 V or to midscale, depending on the model, and remains there until a valid write takes place. The AD5662 is particularly suited for portable battery-operated equipment due to its low power consumption of 0.75 mW at 5 V, which reduces to 2.4 μW in power-down mode.
