DAC 1-CH Current Steering 8-bit 6-Pin TSOT-23

The MAX5385EZT+ low-cost, 8-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 MAX5385EZT+ operates over the full +2.7V to +5.5V supply range and has an internal reference equal to 0.9 x Vdd. The MAX5385EZT+ 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 MAX5385EZT+ include a 1µA, low-power shutdown mode that features software-selectable output loads of 1k?, 100k?, or 1M? to ground.
