Overview
The AD5662BRJZ-2500RL7, produced by Analog Devices Inc., 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. It is part of the nanoDAC family 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 variant. The AD5662 is ideal for applications requiring low power consumption, such as portable battery-operated equipment, with a power consumption of 0.75 mW at 5 V and as low as 2.4 μW in power-down mode.
