U1 is a single channel opamp, that's why power connects to 7 instead of 8. That's the standard pinout for single opamps. Pins 1 & 8 are typically for connecting a compensation cap, such as is done here. All the opamps in this design are singles.Also somebody please help me understand the function of U1 In this circuit. Since the possitive power is connected to 7 instead of 8
Functionally, U1 is wired as a balanced line receiver.
