Hey all.
I saw the thread "Dual or single supplies for opamps" - but there are no information about IN, so I need to ask u the question:
I have a ciruit as shown in the jpg image.
when known:
Vdc>0
V1<=Vdc
Vout>0
In the calculation I have -R1/R2*Vdc, but Vout always positive.
Can I conenct the amp to single power supply or I have connect it to the dual one.
please explane.
thanks ahead.
