DAC101C081/ DAC101C085 10-Bit Micro Power Digital-to-Analog Converter with an I2C-Compatible Interface

The DAC101C081 is a 10-bit, single channel, voltage-output digital-to-analog converter (DAC) that operates from a +2.7V to 5.5V supply. The output amplifier allows rail-to-rail output swing and has an 6μsec settling time. The DAC101C081 uses the supply voltage as the reference to provide the widest dynamic output range and typically consumes 132μA while operating at 5.0V. It is available in 6-lead TSOT and LLP packages and provides three address options (pin selectable). As an alternative, the DAC101C085 provides nine I2C addressing options and uses an external reference. It has the same performance and settling time as the DAC101C081. It is available in an 8-lead MSOP. The DAC101C081 and DAC101C085 use a 2-wire, I2C-compatible serial interface that operates in all three speed modes, including high speed mode (3.4MHz). An external address selection pin allows up to three DAC101C081 or nine DAC101C085 devices per 2-wire bus. Pin compatible alternatives to the DAC101C081 are available that provide additional address options.
