Low-Cost, Low-Power 6-Bit DACs with
2-Wire Serial Interface in SOT23 Package
General Description
The MAX5360/MAX5361/MAX5362 are low-cost, 6-bit
digital-to-analog converters (DACs) in miniature 5-pin
SOT23 packages with a simple 2-wire serial interface
that allows communication with multiple devices. The
MAX5360 has an internal +2V reference and operates
from a +2.7V to +3.6V supply. The MAX5361 has an
internal +4V reference and operates from a +4.5V to
+5.5V supply. The MAX5362 operates over the full
+2.7V to +5.5V supply range and has an internal refer-
ence equal to 0.9
V
DD
.
The fast-mode I
2
C-compatible serial interface allows
communication at data rates up to 400kbps, minimizing
board space and reducing interconnect complexity in
many applications. Each device is available with one of
four factory-preset addresses (see
Selector Guide).
The MAX5360/MAX5361/MAX5362 also include an out-
put buffer, a low-power shutdown mode, and a power-
on reset that ensures the DAC outputs are at zero when
power is initially applied. In shutdown mode, the supply
current is reduced to less than 1µA and the output is
pulled down with a 10kΩ resistor to GND.
The MAX5360/MAX5361/MAX5362 are available in
miniature 5-pin SOT23 packages.

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.
