low voltage analog signal passing through microcontroller
February 17, 2018 - 10:35pm

Can microcontroller work like switches for low voltage analog signal. I mean when press the button signal (less than 300 mV, very low amperage) pass unchanged through microcontroller (one analog input, one analog output), than by software disable input and output or simply turn off power (same button)? I want to solve that without external switches and relays. Thanks.

You can use the ADC feature

You can use the ADC feature in microcontroller. If that's what you are looking for.
