General Description
The MAX5141–MAX5144 are serial-input, voltage-output,
14-bit digital-to-analog converters (DACs) in tiny μMAX
packages, 50% smaller than comparable DACs in an
8-pin SO. They operate from low +3V (MAX5143/
MAX5144) or +5V (MAX5141/MAX5142) single supplies.
They provide 14-bit performance (±1LSB INL and DNL)
over temperature without any adjustments. The DAC out-
put is unbuffered, resulting in a low supply current of
120μA and a low offset error of 2LSBs.
The DAC output range is 0V to V
REF.
For bipolar opera-
tion, matched scaling resistors are provided in the
MAX5142/MAX5144 for use with an external precision 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 (MAX5141/MAX5143) or code 8192 (MAX5142/
MAX5144) when power is initially applied.
A logic low on
CLR
asynchronously clears the DAC out-
put to code 0 (MAX5141/MAX5143) or code 8192
(MAX5142/MAX5144), independent of the serial interface.
The MAX5141/MAX5143 are available in 8-pin μMAX
packages and the MAX5142/MAX5144 are available in
10-pin μMAX packages.
