Hello,
I have a question about acquisition time in "configure ADC".
In "General" tab, I set "Clock frequency(kHz):" to 16000kHz.
In "Channels" tab, I set "A cloks:" to 5. So, the acquisition time should be 312.5ns.
Why?
In the case of 281.25ns, the ADC clock frequency will be 17.777MHz.
The conversion time seems to be correct.
Conversion time = (5+14)/16MHz = 1.1875 us
Conversion time means the total acquisition time and conversion time.
Best regards,
Yocchi

Hi,
The actual sample time is modified by changing the register setting SAMPLE_TIME0/1/2/3
See the register definition. The actual sample time will half cycles less(4.5 times in your case)

Hello Vasanth-san,
Thank you very much for your reply.
if the sample time is 4.5cycles, the conversion time is 1.156us[(4.5+14)/16MHz].
The conversion time error will increase.

Hello Vasanth-san,
The conversion time error will increase, right?
