What is the difference between ADCP,ADCSA and ADCE on S32K3

[Guofred]

Dear Sir,

What is the difference between ADCP,ADCSA and ADCE on S32K3

ADCP: Precision mode, the covert data width is around 15

ADCS: Standard mode,  it is normal mode, 12bit ADC

ADCE: External mode , one multiplexer has 8 channels,  4 multiplexer are around 32 channels.

we can set the MCR registor to Enable the different ADC conversion mode, my understanding is right or

not, would you like kindly help to share your comments, thanks.

I don't understand your description too much.

There are three typed of ADC channels on the device. Standard and Precision differs in offered precision, external channels offering adding of external multiplexer to increase number of inputs.

Hi @davidtosenovjan ,

Yes, thanks for your kindly help.

would you like kindly help to share the differ of the offered precision between standard and precision.

such as standard type ADC channel has 12 bit resolution,  precision type ADC channel has 15 bit

resolution, my understanding is right or not, kindly help to share your comments, thanks. 

Best regards.

From functional point of view ADC conversions are the same with configurable resolution:

The difference see in datasheet specification:
