The MAX5544 serial-input, voltage-output, 14-bit
monotonic digital-to-analog converter (DAC) operates
from a single +5V supply. The DAC output is
unbuffered, resulting in low 0.3mA supply current and
low 1LSB offset error. The DAC output range is 0V to
V
power-on reset 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
MAX5544 is available in an 8-pin SO package.
