Overview
The AD5664BCPZ-R2, produced by Analog Devices Inc., is a member of the nanoDAC® family. It is a low-power, quad, 16-bit buffered voltage-out digital-to-analog converter (DAC) that operates from a single 2.7 V to 5.5 V supply. This device is guaranteed monotonic by design and features a rail-to-rail output swing, making it suitable for a variety of applications requiring high precision and low power consumption.
The AD5664BCPZ-R2 includes a power-on reset circuit that ensures the DAC output powers up to 0 V and remains there until a valid write takes place. It also has a power-down feature that reduces the current consumption to 480 nA at 5 V, with software-selectable output loads in power-down mode. This makes it ideal for portable battery-operated equipment.
