+3V/+5V, Serial-Input,
Voltage-Output, 14-Bit DACs
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 VREF. 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 ±VREF 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.

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.
