MAX5360/MAX5361/MAX5362 19-1785 Rev 2 3/11 Low-Cost, Low-Power 6-Bit DACs with 2-Wire Serial Interface in SOT23 Package General Description Features The MAX5360/MAX5361/MAX5362 are low-cost, 6-bit 6-Bit Accuracy in a Tiny 5-Pin SOT23 Package digital-to-analog converters (DACs) in miniature 5-pin Wide +2.7V to +5.5V Supply Range (MAX5362) SOT23 packages with a simple 2-wire serial interface that allows communication with multiple devices. The 1A Shutdown Mode MAX5360 has an internal +2V reference and operates Buffered Output Drives Resistive Loads from a +2.7V to +3.6V supply. The MAX5361 has an Low Glitch Power-On-Reset to Zero DAC Output internal +4V reference and operates from a +4.5V to +5.5V supply. The MAX5362 operates over the full 2 Fast I C-Compatible Serial Interface +2.7V to +5.5V supply range and has an internal refer- -5% Full-Scale Error (MAX5362) ence equal to 0.9 V . DD 2 1LSB (max) INL/DNL The fast-mode I C-compatible serial interface allows communication at data rates up to 400kbps, minimizing Low 230A max Supply Current board space and reducing interconnect complexity in Ordering Information many applications. Each device is available with one of four factory-preset addresses (see Selector Guide).

In shutdown mode, the supply MAX5362 EUK +T* -40C to +85C5 SO T23-5 current is reduced to less than 1A and the output is *See Selector Guide for address options. pulled down with a 10k resistor to GND. +Denotes a lead(Pb)-free/RoHS-compliant package. The MAX5360/MAX5361/MAX5362 are available in Selector Guide miniature 5-pin SOT23 packages.
