Hi,
yes sorry it is a LTC1400, 12 bits 400 ksamples SAR ADC from linear technology.
However the datasheet states: No Missing Codes over Temperature
which should mean no missing codes up to 12 bits ...
For what concerns the test, the input signal is almost constant, so it is spread over something like 80 channels, this means that 1000
samples are enough. I tried also 5000 with the same result. The missing
codes are still there and seem almost the same from one run to the other.
Do you really think that it could be the standard working mode for this ADC ?
thanks a lot
