Question about SAR ADC in STM32H753

[RongShengWang]

Questions:

1. Does STM32H753 have three independent 16-bit SAR ADC modules?

    Any other STM32 parts also have 16-bit SAR ADC modules?

2. Can a selected channel in each 16-bit SAR ADC module (Totally 3 selected channel in the 3 modules) be sampled simultaneously under the same clock rate?

3. How are the Direct /Fast /Slow channels in SAR ADC defined?

4. Which STM32H753 is used in NUCLEO board? (VI, ZI, AI......)

Thanks,

Rong

1. look in ds. + yes, see cpu selection tool.

2. yes

3. see in ds . The analog mux makes some channels a little bit faster - or slower.

4. just check from the boards avail.

Below shows  having 3 of16-bit ADCs - Are they independent?

Below shows STM32H753ZI has 2 direct channels, 9 fast channels, 17 slow channels.

                                              Are they independent? Or only  2 direct channels independent?

Thanks

yes.

yes, independent .

 

see AN5354 :

You should read yourself, see rm :

So 1+2 can work in dual mode...but also separate.
