ADC and DAC max sampling rate?

Official Hardware Portenta Family Portenta C33
1

In reading the datasheet for the Portenta C33, it doesn't explain the maximum sampling rate of the ADC (it only says it is 12 bits). The same is true for the DAC.

If I Google the string "R7FA6M5BH2CBG sampling rate" I get no hits.

The user guide doesn't specify.

Please help! This might be a great board but I'm trying to do audio processing (in/out) and need to handle audio frequencies up to ~6KHz so I need a sampling rate well above 12KHz. I hope I can get up to 20KHz sampling rate in/out. Often ADC's are much slower than DAC's, so I'm interested in both numbers for this board.

Thanks!

Of course not. The details will be in the processor data sheet, ADC and DAC sections. You can download it from Renesas, or a reputable supplier.

But, even the lowly Arduino Uno, with the 30 year old ATMega328 can handle 6 kHz audio input. It just doesn't have enough memory to store a decent number of samples.

What prevents you from finding out for yourself? For example, take 100 or 1000 measurements and detect how many microseconds have passed. Or read the datasheet where it says this at the beginning:
