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



The fast-mode I

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.
