Hello

I need to do simultaneous sampling of 2 analogue signals using the 12bit ADC in the LPC4370.

The data sheet shows a 6:1 MUX at the input of the ADC but I did not find a detail description so I assume the sampling is only done in the ADC block so all that can be done is sequential sampling.

Can anyone comment / confirm my understanding is correct?

Thanks!

Yes that is correct... with the 80MSps 12bit ADC only sequential sampling is possible.
