The input data are written to the individual DAC Data registers in straight binary format for all output ranges. The DAC transfer function is given by Equation 1.
Equation 1. where:
- CODE is the decimal equivalent of the binary code that is loaded to the DAC register. CODE range is from 0 to 2n – 1.
- n is the DAC resolution in bits. Either 12 (DAC61416), 14 (DAC71416) or 16 (DAC81416).
- FSR is the DAC full-scale range. Equal to VMAX – VMIN for the selected DAC output range.
- VMIN is the lowest voltage for the selected DAC output range.
