FSV / 65,536 * CODE = OutV or CODE = OutV / FSV * 65,536

For Example:

If the range is 0 to 5V CODE = 2/5 * 65,536

and you desire a 2V output. CODE = 26,214

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 CODE = (−7V + 0.5 * 20) / 20 * 65,536

and you desire a −7V output. CODE = 9,830
