I am working with a microcontroller with 8-channel, 10 bit multiplexer A/D converter. In the manual it says: When a sequence consists of multiple samples, the samples may be taken from one channel or multiple channels. An interrupt may be generated on the completion of an A/D conversion. The analog multiplexer selects one of the three internal or one of the external signal sources for conversion.
So the questions are:
1- When we have a multiplexer at the input, does it mean that I can sample 8 different signals simultaneously?
2- I am trying to measure the temperature with the MCU and I am not sure what three internal signals mean. I guess in my case I just have one external signal, right?
