• Code is the raw count used by the software to represent the
voltage.
• Vout is the analog voltage.
• Offset is the minus full-scale value, or
−5
V.
For example, if you want to output a voltage of 4.7 V, determine the
code value as follows:
LSB = 10 V = 0.0001526 V
65536
Code = 4.7 V - (-5 V)
0.0001526 V
Code = 63565 = 784Dh
