The MAX5363/MAX5364/MAX5365 low-cost, 6-bit digital- to-analog converters (DACs) in miniature 6-pin SOT23 packages have a simple 3-wire, SPI™/QSPI™/MICROWIRE™-compatible serial interface that operates up to 10MHz. The MAX5363 has an internal +2V reference and operates from a +2.7V to +3.6V supply. The MAX5364 has an internal +4V reference and operates from a +4.5V to +5.5V supply. The MAX5365 operates over the full +2.7 to +5.5V supply range and has an internal reference equal to 0.9 x VDD.

The MAX5363/MAX5364/MAX5365 require an extremely low supply current of only 150µA (typ) and provide a buffered voltage output. These devices power up at zero code and remain there until a new code is written to the DAC registers. This provides additional safety for applications that drive valves or other transducers that need to be off on power-up. The MAX5363/MAX5364/MAX5365 include a 1µA, low-power shutdown mode that features software-selectable output loads of 1kΩ, 100kΩ, or 1MΩ to ground.
