hi all,
i am detecting phase shift between two signals feeding to COMMON IN and SIG in . i had issue where PC2out was dead . I solved issue by adding 2k /2k to 5v and gnd . i dont understand why it needs resistors their .
another question is now i can see signal in oscilloscope based on lead and lag . how can i read using microcontroller . do i need to add any filter between ic and microcontroller .
