FSV / 65,536 * CODE = OutV
For Example:
If the range is 0 to 5V
and you desire a 2V output.
The BIPOLAR transfer function for the DAC is:
FSV/65,536 * CODE − 0.5 * FSV or CODE = (OutV + 0.5 * FSV) / FSV * 65,536
For example:
If the range is set to ±10
and you desire a −7V output.
or
CODE = OutV / FSV * 65,536
CODE = 2/5 * 65,536
CODE = 26,214
CODE = (−7V + 0.5 * 20) / 20 * 65,536
CODE = 9,830
