Other Parts Discussed in Thread: ADS1247
My customer is considering ADS1147 and has a question about input channel crosstalk.
I would be grateful if you could advise.
I have a question about the internal multiplexer of the ADS1247.
What is the crosstalk characteristic of adjacent channels in dB?
For example, when the maximum voltage is input to AINP1-AINN1 and the minimum voltage is input to AINP2-AINN2 and A/D conversion is performed, what is the effect of crosstalk?
A typical multiplexer has about 90dB of crosstalk between adjacent channels, but I think this is insufficient.
I appreciate your great help in advance.
