Hello fellows,
I have the attached analog circuitry attached to an ADC, I am trying to understand what each step does, i figured out a couple but i am really struggling to understand the others (not so good with analog circuitry) I wish if someone can help telling me what each op Amp does to the signal.
the sensor i have is an accelerometer and its piezoelectric, will attach its response as well as the response at the input of the ADC.
the current ADC is https://datasheets.maximintegrated.com/en/ds/ICL7106-ICL7107.pdf, and I am trying to use a PIC MCU instead so any suggestions are welcome.
Regards.
