I am using LTC2323-16, as I/V simultaneous sampling. For LTC2323, in spec page7, Offset error and Gain error temp curve are there, combine with Page11 fig2 transfer function curve to adjust system setting. Is it right solution for temp co. compensation? Besides, where I can find the INL curve? I mean, I need to find a solution to minimize the INL error using curve fitting. Basically, I want less than 2LSB INL. LTC2323-16 is good part for SPS and Bits demand. But INL is not good enough, or other new part can be introduced?
I found that, in small signal, or say the mV level input, the INL is not stable, if we amplify the same signal, say X2, or X4, the INL will be improved. For this part, in near GND swing, the C cap tree induced more error caused SNR is dropped? What is the Ideal input range to get best INL performance?
