3 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 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-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.
