GENERAL DESCRIPTION
The AD5305/AD5315/AD53251 are quad 8-, 10-, and 12-bit
buffered voltage output DACs in a 10-lead MSOP 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 that
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.
The references for the four DACs are derived from one
reference pin. The outputs of all DACs can be updated
simultaneously using the software LDAC function.
The parts incorporate a power-on reset circuit, which ensures
that the DAC outputs power up to 0 V and remain there until a
valid write takes place to the device. There is also a software
clear function to reset all input and DAC registers to 0 V. The
parts contain a power-down feature that reduces the current
consumption of the devices to 200 nA @ 5 V (80 nA @ 3 V).
The low power consumption of these parts in normal operation
makes them ideally suited for portable battery-operated equip-
ment. The power consumption is 3 mW at 5 V, 1.5 mW at 3 V,
reducing to 1 μW in power-down mode.
