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
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.
