Overview
The AD5333BRUZ-REEL, produced by Analog Devices Inc., is a dual 10-bit digital-to-analog converter (DAC) designed for a wide range of applications requiring precision and low power consumption. This device operates from a 2.5 V to 5.5 V supply, consuming only 230 µA at 3 V, and features a power-down mode that reduces current to 80 nA. The AD5333BRUZ-REEL is packaged in a 24-lead Thin Shrink Small Outline Package (TSSOP) and is suitable for use in portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, and industrial process control.
