Overview
The AD5425YRM-REEL7 is a CMOS, 8-bit, current output digital-to-analog converter (DAC) produced by Analog Devices Inc. This DAC operates from a 2.5 V to 5.5 V power supply, making it suitable for battery-powered applications and a variety of other uses. It features a double-buffered, 3-wire serial interface compatible with SPI®, QSPI™, MICROWIRE™, and most DSP interface standards. The device includes an active-low LDAC pin for simultaneous updates in multi-DAC configurations. On power-up, the internal shift register and latches are initialized with zeros, and the DAC outputs are set to 0 V.
