Description 

The DAC081C08x device is an 8-bit, single-channel, voltage-output digital-to-analog converter (DAC) that operates from a 2.7-V to 5.5-V supply. The output amplifier allows rail-to-rail output swing and has an 4.5-µsec settling time. The DAC081C081 uses the supply voltage as the reference to provide the widest dynamic output range and typically consumes 132 µA while operating at 5 V. It is available in 6-lead SOT and WSON packages and provides three address options (pin selectable). As an alternative, the DAC081C085 provides nine I 2C addressing options and uses an external reference. It has the same performance and settling time as the DAC081C081. It is available in an 8-lead VSSOP. The DAC081C081 and DAC081C085 use a 2-wire, I 2C-compatible serial interface that operates in all three speed modes, including high-speed mode (3.4 MHz). An external address selection pin allows up to three DAC081C081 or nine DAC081C085 devices per 2-wire bus. Pin-compatible alternatives to the DAC081C081 are available that provide additional address options.
