Overview
The AD5306BRU-REEL7 is a quad 8-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This component is part of the AD5306/AD5316/AD5326 family and is housed in a 16-lead TSSOP package. It operates from a single supply voltage ranging from 2.5 V to 5.5 V, making it versatile for various applications. The device features on-chip output amplifiers that allow rail-to-rail output swing and a 2-wire serial interface compatible with SMBus at VDD < 3.6 V. This interface supports clock rates up to 400 kHz and allows multiple devices to be placed on the same bus.
