Status
Active: In Production.
Description
The MAX5380/MAX5381/MAX5382 are low-cost, 8-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
MAX5380 has an internal +2V reference and operates
from a +2.7V to +3.6V supply. The MAX5381 has an
internal +4V reference and operates from a +4.5V to
+5.5V supply. The MAX5382 operates over the full
+2.7V to +5.5V supply range and has an internal reference
equal to 0.9 x VDD.
The fast-mode I²C*-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).
These DACs also include an output 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, supply current is reduced to less
than 1µA and the output is pulled down to GND with a
10kΩ resistor.
