产品概述

The MAX5380/MAX5381/MAX5382 are low-cost, 8-bitdigital-to-analog converters (DACs) in miniature 5-pinSOT23 packages, with a simple 2-wire serial interfacethat allows communication with multiple devices. TheMAX5380 has an internal +2V reference and operatesfrom a +2.7V to +3.6V supply. The MAX5381 has aninternal +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 referenceequal to 0.9 x VDD.

The fast-mode I²C*-compatible serial interface allowscommunication at data rates up to 400kbps, minimizingboard space and reducing interconnect complexityin many applications. Each device is available withone of four factory-preset addresses (see SelectorGuide).These DACs also include an output buffer, a low-powershutdown mode, and a power-on reset that ensures theDAC outputs are at zero when power is initially applied.In shutdown mode, supply current is reduced to lessthan 1µA and the output is pulled down to GND with a10kΩ resistor.
