3 Description
The DAC101C081 device is a 10-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 6-
µsec settling time. The DAC101C081 uses the supply
voltage as the reference to provide the widest
dynamic output range and typically consumes 132 µA
while operating at 5.0 V. It is available in 6-lead SOT
and WSON 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 and is available in an 8-
lead VSSOP.
The DAC101C081 and DAC101C085 use a 2-wire,
I2C-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 DAC101C081 or nine DAC101C085 devices
per 2-wire bus. Pin compatible alternatives to the
DAC101C081 are available that provide additional
address options.
