Overview
The AD5306BRUZ, produced by Analog Devices Inc., is a quad 8-bit buffered voltage output Digital-to-Analog Converter (DAC) designed for a wide range of applications. This device operates from a single 2.5 V to 5.5 V supply and is housed in a 16-lead TSSOP package. It is part of the AD5306/AD5316/AD5326 family, offering different resolutions but sharing the same pinout, which allows for easy migration between different resolution requirements without redesigning the circuit board.

Key Features
- Quad 8-bit buffered voltage output DACs.
- Operates from a single 2.5 V to 5.5 V supply.
- On-chip output amplifiers allow rail-to-rail output swing with a slew rate of 0.7 V/μs.
- 2-wire serial interface compatible with SMBus at VDD < 3.6 V, with clock rates up to 400 kHz.
- Multiple devices can be placed on the same bus.
- Each DAC has a separate reference input that can be configured as buffered or unbuffered.
- Outputs of all DACs can be updated simultaneously using the asynchronous LDAC input.
- Power-on reset circuit ensures DAC outputs power up to 0 V and remain there until a valid write to the device takes place.
- Software clear function clears all DACs to 0 V.
- Power-down feature reduces current consumption to 300 nA @ 5 V (90 nA @ 3 V).
