Full Scale Gain Error (FS Gain)
The full scale gain error measurement determines the difference
between the expected and the real output voltage at maximal code.
The gain error is also called proportional displacement.
You can choose between several measurement units.
The software provides two calculation alternatives:
• Nominal calculation
• Device-dependent calculation
The nominal calculation refers to an ideal DAC, the device-
dependent calculation takes the measured offset into account.
Definition of Device-Dependent Full Scale Gain Error
For more information about the calculation of the Full Scale Gain
Error, see the Appendix “Definition of DAC and ADC
Characteristics” on page 567.
DAC LSB Gain Error
The LSB gain error is a measure of the error between the LSB of
an ideal DAC (LSB
nom) and the actual DeviceLSB.
There are several ways to calculate the LSB gain error, for
example, in % of LSB
nom, or in % of DeviceLSB.
The FS gain error is a measure of the output error between an ideal
DAC and the actual device at full scale output.
