We have reproduced the whole evaluation bord circuirty, so the hw should be out of discussion.
We apply a differential voltage to the inputs of a given channel and read a value of 8755d0, instead of the value calculated with formula on page 24; Code = 2N – 1 × ((VIN × 0.1/VREF) + 1)
What suggst for this?
Other question is if gain and offset are always applied to the raw date read from the AD. If I apply the formula on page 32; Data = ((0.075 × VIN/VREF) × 223 – (Offset − 0x800000)) × (Gain/0x400000) + 0x800000 I get a different results, apart for the default gain of 0x5XXXX0, where I don't understand what the "XXXXX" value means, because if you use it for a multiplication the result can be influenced by the current value.
Thank you in advance for your replay.
