+3V/+5V, Serial-Input, Voltage-Output, 16-Bit DACs
General DescriptionThe MAX5441–MAX5444 are serial-input, voltage-out-
put, 16-bit digital-to-analog converters (DACs) in tiny
µMAX packages, 50% smaller than comparable DACs
in 8-pin SOs. They operate from low +3V (MAX5443/
MAX5444) or +5V (MAX5441/MAX5442) single sup-
plies. They provide 16-bit performance (±2LSB INL and
±1LSB DNL) over temperature without any adjustments.
Unbuffered DAC outputs result in a low supply current
of 120µA and a low offset error of 2LSB.
The DAC output ranges from 0 to VREF. For bipolar
operation, matched scaling resistors are provided in
the MAX5442/MAX5444 for use with an external preci-
sion op amp (such as the MAX400), generating a
±VREFoutput swing.
A 16-bit serial word is used to load data into the DAC
latch. The 25MHz, 3-wire serial interface is compatible
with SPI™/QSPI™/MICROWIRE™, and can interface
directly with optocouplers for applications requiring isola-
tion. A power-on reset circuit clears the DAC output to
code 0 (MAX5441/MAX5443) or code 32768 (MAX5442
/MAX5444) when power is initially applied.
A logic low on CLRasynchronously clears the DAC out-
put to code 0 (MAX5441/MAX5443) or code 32768
(MAX5442/MAX5444) independent of the serial interface.
The MAX5441/MAX5443 are available in 8-pin µMAX
packages. The MAX5442/MAX5444 are available in 10-
pin µMAX packages.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
