GENERAL DESCRIPTION

The AD5306/AD5316/AD5326

voltage output DACs in 16-lead TSSOP packages that operate

from a single 2.5 V to 5.5 V supply, consuming 500 μA at 3 V.

Their on-chip output amplifiers allow rail-to-rail output swing

with a slew rate of 0.7 V/μs. A 2-wire serial interface, which

operates at clock rates up to 400 kHz, is used. This interface is

SMBus-compatible at V

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 0 V and remain there until a valid

write to the device takes place. The software clear function

clears all DACs to 0 V. The parts contain a power-down feature

that reduces the current consumption of the device to

300 nA @ 5 V (90 nA @ 3 V).

All three parts have the same pinout, which allows users to select

the amount of resolution appropriate for their application without

redesigning their circuit board.

AD5306/AD5316/AD5326 WRITE OPERATION When writing to the AD5306/AD5316/AD5326 DACs, the user must begin with an address byte ( 0), after which the DAC acknowledges that it is prepared to receive data by pulling SDA low. This address byte ...
