Low-Cost, Low-Power, 6-Bit DACs with 3-Wire
Serial Interface in SOT23
General Description
The MAX5363/MAX5364/MAX5365 low-cost, 6-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 MAX5363 has an internal +2V refer-
ence and operates from a +2.7V to +3.6V supply. The
MAX5364 has an internal +4V reference and operates
from a +4.5V to +5.5V supply. The MAX5365 operates
over the full +2.7 to +5.5V supply range and has an
internal reference equal to 0.9
✕
V
DD
.
The MAX5363/MAX5364/MAX5365 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
applications that drive valves or other transducers that
need to be off on power-up. The MAX5363/MAX5364/
MAX5365 include a 1µA, low-power shutdown mode
that features software-selectable output loads of 1kΩ,
100kΩ, or 1MΩ to ground.

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.
