16-lead TSSOP package

Micropower operation: 300 μA @ 5 V (including reference

current)

Power-down to 200 nA @ 5 V, 50 nA @ 3 V

2.5 V to 5.5 V power supply

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

SDO daisy-chaining option

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.

APPꢀICATIONS

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.
