Overview
The AD5674RBCPZ-1-RL7 is a low-power, 16-channel, 12-/16-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This device features buffered voltage output and includes a 2.5 V internal reference with a temperature coefficient of 2 ppm/°C. It operates from a single supply voltage range of 2.7 V to 5.5 V and is available in a 28-lead lead frame chip scale package (LFCSP). The AD5674RBCPZ-1-RL7 is designed for applications requiring high precision and reliability, with features such as user-selectable gain of 1 or 2 and a 50 MHz serial peripheral interface (SPI) with readback or daisy chain capabilities.
