The circuit is a good recommended line circuit.First of all,it uses high precision voltage regulation circuit composed of TL431 with DIP encapsulation .The dissipation power reaches 1W because TL431 uses DIP encapsulation and it's easy to change dividing resistor by altering power supply voltage.Second,operational amplifiers choose the high precision and low disorders, OP07 and its parameter index is much better than common cheap op-amp.The key is that the output voltage of the op-amp ICC is equal to zero when the input is four mA on zero signal processing. Work Principle of this Part CircuitThe same phase input port voltage of Op-amp ICD is porvided by negative power which regulated by TIA31 and it divides voltage via R15 and R14.
