MAX5385EUT+T
The MAX5383/MAX5384/MAX5385 low-cost, 8-bit digital-
to-analog converters (DACs) in miniature 6-pin SOT23
packages have a simple 3-wire, SPI™/QSPI™/
MICROWIRE™-compatible serial interface that operates
up to 10MHz. The MAX5383 has an internal +2V refer-
ence and operates from a +2.7V to +3.6V supply. The
MAX5384 has an internal +4V reference and operates
from a +4.5V to +5.5V supply. The MAX5385 operates
over the full +2.7V to +5.5V supply range and has an
internal reference equal to 0.9
The MAX5383/MAX5384/MAX5385 require an extremely
low supply current of only 150µA (typ) and provide a
buffered voltage output. These devices power up at zero
code and remain there until a new code is written to the
DAC registers. This provides additional safety for appli-
cations that drive valves or other transducers that need
to be off on power-up. The MAX5383/MAX5384/
MAX5385 include a 1µA, low-power shutdown mode that
features software-selectable output loads of 1kΩ, 100kΩ,
or 1MΩ to ground.
