What do you mean by threshold voltagehi,
It is wired as a Comparator, with hysteresis, R8 and R9 set the threshold voltage level.

Thank you.I understood.hi,
When using a comparator you need to have a Threshold voltage on one of the OPA pins against which the incoming signal is compared.
If the incoming voltage is less than the threshold voltage the OPA output is at one state, when the incoming voltage is greater than the threshold voltage the output of the OPA is in the other state.
OK.?
