Overview
The AD5424YCPZ-REEL7, produced by Analog Devices Inc., is a high-bandwidth CMOS 8-bit current output digital-to-analog converter (DAC). This device is part of the AD5424/AD5433/AD5445 family, which includes 8-, 10-, and 12-bit DACs, respectively. The AD5424 operates from a 2.5 V to 5.5 V power supply, making it suitable for battery-powered applications and various other uses. It features a fast parallel interface with a write cycle time of 17 ns and an update rate of 20.4 MSPS. The DAC is manufactured using a CMOS submicron process, ensuring excellent 4-quadrant multiplication characteristics and a large signal multiplying bandwidth of up to 10 MHz.
