Overview
The AD5426YRMZ-REEL is a high-performance, 8-bit current output digital-to-analog converter (DAC) produced by Analog Devices Inc. This device is part of the AD5426/AD5432/AD5443 family, which includes 8-, 10-, and 12-bit DACs, respectively. The AD5426YRMZ-REEL operates from a 2.5 V to 5.5 V power supply, making it suitable for a wide range of applications, including battery-powered devices and other low-voltage systems.
The DAC features a double-buffered, 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and most DSP interface standards. It also includes a serial data out pin (SDO) for daisy-chaining multiple packages and a readback function to read the contents of the DAC register via the SDO pin.
