Overview
The AD5308BRUZ, manufactured by Analog Devices Inc., is an octal 8-bit buffered voltage output Digital-to-Analog Converter (DAC) packaged in a 16-lead TSSOP. This device is part of the AD5308/AD5318/AD5328 family, which includes 8-, 10-, and 12-bit resolutions, respectively. The AD5308 operates from a single supply voltage ranging from 2.5 V to 5.5 V and consumes a typical current of 0.7 mA at 3 V. It features on-chip output amplifiers that allow rail-to-rail output swing with a slew rate of 0.7 V/μs. The device is designed for various applications requiring multiple DAC channels with high precision and reliability.
