The AD5306 are quad 8-bit buffered voltage output DACs in 16-lead TSSOP packages that operate from a single 2.5V to 5.5V supply, consuming 500uA at 3V. Their on-chip output amplifiers allow rail-to-rail output swing with a slew rate of 0.7V/us. 2-wire serial interface, which operates at clock rates up to 400kHz, is used. This interface is SMBus-compatible at VDD <3.6V. Multiple devices can be placed on the same bus.

Each DAC has a separate reference input that can be configured as buffered or unbuffered. The outputs of all DACs can be updated simultaneously using the asynchronous LDAC input. The parts incorporate a power-on reset circuit that ensures the DAC outputs power up to 0V and remain there until a valid write to the device takes place. The software clear function clears all DACs to 0V. The parts contain a power-down feature that reduces the current consumption of the device to 300nA at 5V (90nA at 3V).
