Description
General part information
DAC121C081 Series
The DAC121C081 is a 12-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 8.5-µs settling time. The DAC121C081 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-pin SOT and WSON packages, and provides three address options (pin selectable).
As an alternative, the DAC121C085 provides nine I2C addressing options and uses an external reference. It has the same performance and settling time as the DAC121C081, and is available in an 8-lead VSSOP.
The DAC121C081 and DAC121C085 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 DAC121C081 or nine DAC121C085 devices per 2-wire bus. Pin compatible alternatives to the DAC121C081 are available that provide additional address options.
