Hi,
Is there a formula to determine the value of CSEN1/2?
The datasheet uses a 680pF capacitor, but I want to check if I can use a 1000pF capacitor. What happens if the CSEN value increases?
Best Regards,
Nishie

Hi Nishie,
There is no formula to determine the value of CSEN1/2. The 680pF value was chosen to work optimally with the internal components to create high-pass pass filter and to reject the AC line frequency (50Hz/60Hz). You can use a larger CSEN capacitor but the insertion loss at the frequency of interest (100kHz-1MHz) drops, I believe.
