Overview
The AD5328ARUZ-REEL7 is a 12-bit octal buffered voltage output Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This component is part of the AD5308/AD5318/AD5328 family, which includes 8-, 10-, and 12-bit resolutions, respectively. The AD5328 operates from a single 2.5 V to 5.5 V supply, consuming a typical 0.7 mA at 3 V. It features on-chip output buffer amplifiers that allow rail-to-rail output swing with a slew rate of 0.7 V/μs. The device is packaged in a 16-lead Thin Shrink Small Outline Package (TSSOP) and is qualified for automotive applications.
