The DACx3204 can operate with the power-supply pin (VDD) as a
reference. Equation 3 shows DAC transfer function when the power-supply pin is used as
reference. The gain at the output stage is always 1x.
- N is the resolution in bits, either 8 (DAC43204), 10 (DAC53204), or 12
- DAC_DATA is the decimal
equivalent of the binary code that is loaded to the DAC-X-DATA bit in the DAC-X-DATA
- DAC_DATA ranges from 0 to
2N – 1.
- VDD is used as the
DAC reference voltage.
