Delsig11 documentation or Toy story
Ant the beginning of documentation there is a line:
"... It is based on a 2.6V full scale input range centered around a user selected AGND, when the reference selection in the global parameter window is set to +/- Bandgap..."
few line later...
The conversion equation governing the 11-bit Delta Sigma ADC is shown below. The equation shows that the input range is limited to Vref. The use of this equations is illustrated in this example:"
First sentense say the measurement range is arounf Vref, the second, that it's limited to Vref.
Does it make sense?
Another example from the same doc
"Data format available in 2’s complement"
And few lines later:
"Left-justified data is stored with the upper 8 bits in the most significant byte and the lower 3 bits in the upper 3 bits of the least significant byte. The lower 5 bits contain residue of the decimator."
Where is a sign bit or it's not a 2's complement anymore?
