Overview
The AD5306ARUZ-REEL7 is a quad 8-bit buffered voltage output Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This component is part of the AD5306/AD5316/AD5326 family, which includes 8-, 10-, and 12-bit versions, respectively. The AD5306 operates from a single 2.5 V to 5.5 V supply, making it suitable for a variety of applications requiring low power consumption and high precision.
The device is packaged in a 16-lead TSSOP package and features on-chip output amplifiers that allow rail-to-rail output swing with a slew rate of 0.7 V/μs. It also includes a 2-wire serial interface compatible with SMBus at VDD < 3.6 V, enabling multiple devices to be placed on the same bus.
