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 I2C 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, I2C-patible 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-patible alternatives to the DAC081C081 are available that provide additional address options. Table 1.
