General Description
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 I
2C 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, I
2C-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.
The DAC101C081 and DAC101C085 each have a 16-bit register that controls the mode of operation, the power-down condition, and
the output voltage. A power-on reset circuit ensures that the DAC output powers up to zero volts. A power-down feature reduces
power consumption to less than a microWatt. Their low power consumption and small packages make these DACs an excellent choice
for use in battery operated equipment. Each DAC operates over the extended industrial temperature range of −40°C to +125°C.
The DAC101C081 and DAC101C085 are each part of a family of pin compatible DACs that also provide 12 and 8 bit resolution.
For 12-bit DACs see the DAC121C081 and DAC121C085. For 8-bit DACs see the DAC081C081 and DAC081C085.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
