Datasheet states that analogue input range (value of charging capacitors) e.g. for range 6 is 300±30pC.
1. Is it possible in very worst case that inside one chip and in worst case one channel has 270pC and another 330pC
2. Is there any specification or results for channel-to-channel performance that you can provide for us?
3. When applying constant and same current (charge) for every channel we see that biggest jumps from-channel to channel are roughly 2,7% (4000/147000 in counts). Can these jumps be explained by the DDC232 chip itself i.e. is my results within you specification?
Answers appreciated.
