Maximum Sampling speed of F28M35H52C
Can anyone please advice me of the maximum sampling speed of F28M35H52C and also the total conversion time. I can't find it at the datasheet.
The datasheet I have (SPRS742C) states the F28M35H52C ADC is capable of 2.88 MSPS (million samples per second).
This would give an average of 347.22 nS (nano-seconds) per sample.
I hope this answers your questions.
Many thanks to your quick reply. From the link below,
It shows the conversion time to be 172ns. Approximately twice that of F28335. Can you just confirm that? I have one important application for this particular chip.
Many thanks once again.
I do not know if the F28M35H52C website is correct.
I would refer to SPRUH22B (Technical Reference Manual), section 188.8.131.52. which lists the minimum conversion time as 347ns.
F28335 ADC is faster.
I have confirmed that the F28M35H52C ADC has a minimum conversion time of 347ns per ADC. However, since there are two ADC modules, if you run them in parallel you could technically achieve 173.5ns.
F28335 is 80ns.
