Overview
The AD5663RBCPZ-3REEL7, produced by Analog Devices Inc., is a member of the nanoDAC® family. It is a low-power, dual 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 an on-chip 1.25 V or 2.5 V reference with a temperature coefficient of 5 ppm/°C. The AD5663RBCPZ-3REEL7 is housed in a 10-lead LFCSP (3mm x 3mm) package and is suitable for a variety of applications requiring high precision and low power consumption.
