Tool/software:
Hello All from The Capital Of Türkiye!
We are planning to use this ADC in our project. I have different questions regarding:
- Just before ADC's input I want to implement a demux for trying different scenarios.
- Because I do not want to load the sensor's output I am going to use an INA do you have any suggestions? If I go with simple 1:1 muxes should I implement LPF before input pins or can I implement in output too?
- ADC's input defined as 1Mohm and purely resistive;
- ADC has internal LPFs and digital filters but I still want to implement a low pass filter just before the inputs, how should I understand this input impedance. Is it seriesly connected to both negative and positive or is is the input impedance between negative and positive (parallel), since this going to define my bandwidth it carries great importance.
Thank you for your advices in advance!
