LPC845 sampling time

Good morning, I'm working with an LPC845 microcontroller.

For a specific application I need to know how many TAD implies the sampling process of the A/D converter over the entire conversion time.

I have searched on user manual and datasheet but I haven't found any data about sampling except for the total conversion time that is equal to 25 TAD.

Thank you in advance.

Best regards.

Pasquale Barrega.

Hi Pasquale Barrega,

     The LPC845 didn't provide the other sample time, you can consider the full conversion time as the sample time.

So, if your ADC clock is the maximum data 30Mhz, then you will get the max conversion rate or sample rate 1.2Msample/s.

Wish it helps you!

Have a great day,
Kerry

Hi Pasquale Barrega,

   Could you give me the full name of TAD?

 

Best Regards,
