MAX5380, MAX5381, MAX5382 Low-Cost, Low-Power, 8-Bit DACs With 2-Wire Serial Interface In SOT23

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 IC*-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 1A and the output is pulled down to GND with a 10k resistor.
