Hi community team,
I'm checking an ADC specs of LPC1830 and I have some questions as blew;
1. What is a Ri? The Ri is not shown in "Fig 40. ADC interface to pins" of datasheet.
2. What is the relationship between Rvsi and Ri?
3. What was a calculation process of "Rvsi = 1/(7 x fclk(adc) x Cia)"?
4. Are there any documents which explain a detailed block diagram of ADC.
