MAX5541ESA+T

General Description
The MAX5541 serial-input, voltage-output, 16-bit monoto-
nic digital-to-analog converter (DAC) operates from a
single +5V supply. The DAC output is unbuffered, result-
ing in a low 0.3mA supply current and low 1LSB offset
error. The DAC output range is 0V to V
RE
F
. The DAC
latch accepts a 16-bit serial word. A power-on reset
(POR) circuit clears the DAC output to 0V (unipolar
mode) when power is initially applied.
The 10MHz 3-wire serial interface is SPI™/QSPI™/
MICROWIRE™-compatible and interfaces directly with
optocouplers for applications requiring isolation. The
MAX5541 is available in an 8-pin SO package. For the
1LSB (max) INL version, refer to the MAX541 data sheet.

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.
