Which chip has 16 channels ADC

[ticture]

Hello, I want to sampling voltage of 16 data sources, 8 of them are with amplifier, 8 of them directly connect to ADC pins, but I found that both nRF52810, nRF52832 and  nRF52840 have only 8 ADC pins, so which chip should I choose or how I can sampling voltage of 16 data source within nRF52832?  Looking forward to your reply, thanks

Hello,

None of our nRF51, nRF52, or nRF53 series devices have 16 ADC input channels.
To sample from 16 different sources I would suggest multiplexing the signal(s) input to the nRF device's SAADC.

Best regards,
