GENERAL DESCRIPTION
The AD5306/AD5316/AD53261 are quad 8-/10-/12-bit buffered
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 VDD < 3.6 V. 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 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.
