General Description
The 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 V
REF
. 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
±V
REF
output 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
CLR
asynchronously 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.
