Overview
The AD5672RBRUZ is a low power, octal, 12-bit buffered voltage output digital-to-analog converter (DAC) produced by Analog Devices Inc. This device is part of the nanoDAC+ family and is known for its high performance and precision. It features a 2.5 V, 2 ppm/°C internal reference and a gain select pin, allowing for full-scale output of either 2.5 V or 5 V. The AD5672R operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design. It is available in a 20-lead TSSOP package and includes a power-on reset circuit and a power-down mode to minimize current consumption.
