Overview
The AD5674BCPZ-1-RL7, produced by Analog Devices Inc., is a low-power, 16-channel, 12-bit digital-to-analog converter (DAC) with buffered voltage output. This device features a 2.5 V internal reference with a temperature coefficient of 2 ppm/°C and includes a gain select pin, allowing for full-scale output of either 2.5 V or 5 V. It operates from a single supply voltage range of 2.7 V to 5.5 V and is guaranteed monotonic by design. The AD5674BCPZ-1-RL7 is packaged in a 28-lead lead frame chip scale package (LFCSP) and includes a power-on reset (POR) circuit and a power-down mode to minimize current consumption.
