TMS570LC4357: Noise performance of internal ADC

Michal Matejka

Hi engineer,

I didn't find any information about noise performance (for example SNR) of internal ADC for cpu TMS570LC4357.

Can you refer me to the document that describe this?

Thank for your support

Hello Michal,

No, we don't have those data available. All the performance data we have are listed in datasheet (7.4.3).

hello,

I expected you to have a detailed description about noise performance as a external ADCs.

it pays more attention for a external ADCs.

Even so, thank you for your answer

My test data shows that the SNR is around 68dB, the ENOB is 11 bit.
