Overview
The AD5308BRU-REEL7 is an octal 8-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Analog Devices Inc. This component is part of the AD5308/AD5318/AD5328 family, which includes 8-, 10-, and 12-bit resolutions, respectively. The AD5308BRU-REEL7 operates from a single supply voltage ranging from 2.5 V to 5.5 V and is housed in a 16-lead Thin Shrink Small Outline Package (TSSOP). It is designed for high-performance applications requiring precise and reliable digital-to-analog conversion.
