LM3900 Datasheet PDF
It can not be replaced with a LM op amp. The LM is not a normal OP amp.
LM substitute? | Electronics Forum (Circuits, Projects and Microcontrollers)
The circuit uses a single polarity supply so grounding the non-inverting input of the opamps would cause their outputs to be grounded and they would work like rectifiers. We can call the input resistor R1 and the resistor to ground R2 and the feedback resistor R3.
One of the cool things about the LM is that the input voltage can exceed the supply dafasheet without a lot of fancy stuff. I am surprised to see them in circuits today.
