GENERAL DESCRIPTION
The AD5303/AD5313/AD5323 are dual 8-/10-/12-bit buffered
voltage output DACs in a 16-lead TSSOP package that operate
from a single 2.5 V to 5.5 V supply, consuming 230 μA at 3 V.
Their on-chip output amplifiers allow the outputs to swing rail-to-
rail with a slew rate of 0.7 V/μs. The AD5303/AD5313/AD5323
utilize a versatile 3-wire serial interface that operates at clock
rates up to 30 MHz and is compatible with standard SPI, QSPI,
MICROWIRE, and DSP interface standards.
The references for the two DACs are derived from two reference
pins (one per DAC). These reference inputs may be configured
as buffered or unbuffered inputs. 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 to the device takes
place. There is also an asynchronous active low CLR pin that
clears both DACs to 0 V. The outputs of both DACs may be
updated simultaneously using the asynchronous LDAC input.
The parts contain a power-down feature that reduces the
current consumption of the devices to 200 nA at 5 V (50 nA
at 3 V) and provides software-selectable output loads while
in power-down mode. The parts may also be used in daisy-
chaining applications using the SDO pin.
The low power consumption of these parts in normal operation
makes them ideally suited to portable battery-operated equip-
ment. The power consumption is 1.5 mW at 5 V and 0.7 mW at
3 V, reducing to 1 μW in power-down mode.
