To see the dynamic range in the adau1979 A2D i print out the values of the data grater than 0.9999 and smaller than -0.9999.
For close to 1.0 the values that represent it are 0x7FFFFF and down, and I start getting it when the Vpp in the signal generator is 1050 Vpp.
For the opposite, to get the value smaller than -0.9999 , i see a value of 1700 Vpp in the signal generator.
1 - why is this like this? not symmetric.
2 - The Vrms in the sheet is 4.5. That means i would have expected the maximum values arround 6.12 Volts.
Why is this like this?
