What is the fastest sampling rate that the nRF5 SDK ADC values can be read at?

[duendiad]

I am currently using the nRF5 SDK and want to read ADC values at a rate at 1ns but I am not sure if this possible. I currently have a timer that is able to read values at a sampling rate of 1us but whenever I try to read below this value my program stops reading the ADC values. I was wondering if it was possible to read ADC values at 1ns and if this is the case then how would the approach be for it? (I am currently using a timer)

Thank You

Hello,

The possible sampling rate is determined by the SoC you are working with, not the SDK.
For example, for the nRF52840 the maximum sampling rate of the internal SAADC is 200 kHz.
