Hi!
I'm trying to simulate Single supply opamp with LTspice with no luck at all. (9 volts)
It behaves normally with split supply, so presume the problem is not with the circuit.
The only way it seems to function is if i referenced the feedback resistor to 4.5 and not to ground) and a give the biasing from the AC source.
If i try to bias with a voltage divider from the 9 volt source it does not work, i have the same 4.5 volt DC on the input but it doesn't work anymore it gives me about -40db to -70db ac response and about 7.2 volt DC on the output and i also get this if i reference the feedback resistor to ground
Anyone know why is this or how to make split supply opamp circuits?
