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.
