Hello!
I'm very sorry for my bad english and silly question (i'm just studing) (

The question is: if i use AD8295 to drive a single-supply ADC, like in fig.67 in datasheet (with single-supply and REF=Vs/2, Vs=5V), as i understand, i can have bipolar input signals (my signals are about +-200mV differential and some small common mode). But i can't understand, how it works (why opamp from which inamp consists of in not cut negative signal). Have you got some scheme, that can explain it to me?)

 

Thank you, Maria
