Hi every !
I'm designing a Zero crossing detector with a AD790 , the input is a +/- 10V sinus signal .
Output should be hight if Vin > 0V and low if Vin < 0V
I'is working , BUT a have a lot of oscillation at the output .
Is it possible to add a couple of resistor to make a hystérésis with AD790 ?
How much should be the hystérésis ? ( 10mV , 50 mV ?? )
