Hi,
I would verify that I've understood the reference manual correctly. At page 336 it says that the input resistamce of an ADC input (in round robin mode) is: 3000 [kOhm][MHz] /fmod In my application PCLK2 is 32MHz and the prescaling factor set to 500. According to my calculations the input resistance is 47kOhm. Is this correct?2006-01-02 01:44 AM
Hi Beach,
As you said the constant K is equal to 3000 [kOhm][MHz] by the way the input resistance is 47MOhm not kOhm. With best regards, Hichem ;)2006-01-02 01:58 AM
Aaahhh...
47MOhm was a 'better' value (my fault). That makes it possible to use a lower prescaling factor without getting a redicoulisy low input resistance value. ;) Thanx
