Overview
The AD5308BRUZ-REEL, produced by Analog Devices Inc., is part of the AD5308/AD5318/AD5328 family of octal Digital-to-Analog Converters (DACs). These devices are available in 8-, 10-, and 12-bit resolutions and are packaged in a 16-lead TSSOP. The AD5308 specifically features eight 8-bit buffered voltage output DACs. These DACs operate from a single supply voltage ranging from 2.5 V to 5.5 V and consume a typical current of 0.7 mA at 3 V. The on-chip output amplifiers enable rail-to-rail output swing with a slew rate of 0.7 V/μs, making them versatile for various applications.
