Low-Cost, Low-Power, 8-Bit DACs with
2-Wire Serial Interface in SOT23
General 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 refer-
ence equal to 0.9 x 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
).
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
10k
resistor.
