Overview
The AD5306BRUZ-REEL is a quad 8-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This component operates from a single 2.5 V to 5.5 V supply and is packaged in a 16-lead TSSOP. It features a 2-wire serial interface compatible with SMBus at VDD < 3.6 V, allowing multiple devices to be placed on the same bus. The on-chip output amplifiers provide rail-to-rail output swing with a slew rate of 0.7 V/μs. The device includes a power-on reset circuit and a software clear function, ensuring the DAC outputs power up to 0 V and remain there until a valid write occurs. It also has a power-down feature that reduces current consumption significantly.
