TMS320F28P650DK: Question about ADC behaviour before sampling

Part Number: TMS320F28P650DK


Tool/software:

Hi TI,

just a small question and just to verify:

Does the TMS320F28P650DK ADC-Cores discharge the internal S+H-Capacitor Ch (to VREFLO/GND level) before sampling?

(Never, maybe just after starting a ADC chain or maybe always)?

Datasheet says no, or i cound´t find something in this direction.

But there are some guides out there (Building the SAR ADC model | Video | TI.com) which discharge before sampling.

So woulkd be great to verify, that they truly dont discharge.

With best regards,

Martin
