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.
