Some questions are raised for  OVFR/OVFL pin. When input 1Khz with high amp~7Vpp, we could see the pin asserted. But when input frequency increase to 50khz, we cannot see it asserted.

Could you specify why it cannot work with higher frequency?

How does the working range for OVFR/OVFL pin?

How do we know the input amp is overflow when input frequency is 50Khz? From the other pin?
