Hello Team
There is following mention in ADC3244's DataSheet Page61.
CHA TEST PATTERN
1001 = 8-point sine-wave: data are a repetitive sequence of the
following eight numbers that form a sine-wave:
0, 2399, 8192, 13984,16383, 13984, 8192, 2399.
(Offset binary:
0000, 095F, 2000, 36A0, 3FFF, 36A0, 2000, 095F )
However, real 8-point sine-wave are the following values.
The format is setting of register 09h (the digital output data format).
Output data format=0 (2's compl.)
0000, 0f4b, 15a1, 0f4b, 0000, 30b4, 2a5e, 30b4, ...
Output data format=1 (Offset binary)
0a5e, 10b4, 2000, 2f4b, 35a1, 2f4b, 2000, 10b4, ...
I think that the values of DataSheet are a mistake,
and the real values mentioned above are correct.
