Hello,
We can find "Table 21-2. Negative Input Selection Comparison" in "PSoC 4100S and PSoC 4100S Plus: PSoC 4 Architecture TRM, Document No. 002-10621 Rev. *K ".
note:)I dare to change it to the representation of the data sheet of the analog coprocessor PSoC4A.
I have two questions.
1) Is there any material that expresses the Good and Best of the Maximum SNR with specific numerical values?
It doesn't seem to be on the datasheet.
2)Should the Maximum SNR be set to Best in Single-ended mode as shown in the figure below?
Best regards,
Yocchi

Hi Yocchi san,
The configuration in the diagram won’t necessarily create lower noise since the power-supply noise gets coupled into the negative terminal. Vx in the below chart simply refers to the negative terminal of the source under measurement.

Hi Yocchi san,
I am checking this internally. Please give me some time to get back to you.

Hello Vasanth-san,
If so, how can I get the Maximum SNR Best with Single-ended?
And how about question 1)?
Best regards,
Yocchi
