Overview
The AD5428YRUZ-REEL is a CMOS, 8-bit, dual-channel, current output digital-to-analog converter (DAC) produced by Analog Devices Inc. This device is part of the AD5428/AD5440/AD5447 family, which includes 8-, 10-, and 12-bit DACs, respectively. The AD5428 operates from a 2.5 V to 5.5 V power supply, making it suitable for battery-powered and other low-voltage applications. It features excellent 4-quadrant multiplication characteristics and large signal multiplying bandwidths of up to 10 MHz, thanks to its submicron CMOS process. The device includes a power-on reset, readback function, and integrated feedback resistors for temperature tracking and full-scale voltage output when used with an external precision amplifier.
