I have the pin out but I guess what I'm trying to ask is what pins in the schematic are in use? The schematics I'm familiar with for ics are like this one.

it tells you wich pin goes where. In the schematic I'm having trouble with, there is 4 connections, but wich 4? It has 8 pins. pin 2 is the negative input, pin 3 is the positive input, pin 6 is output, pin 7 is positive voltage in, pin 4 is ground....so pins 1 and 5 is the balance and 8 is nc....so 1,5 and 8 float in this circuit?
