ide the differential input stage inverting input terminal and non-inverting input, the amplified signal from 12 feet out, after by the Rflash, R2, R3, C7, C8, C9 network of output. Resistance between 13,5 feet Rf is the feedback network, the output from the expansion of the dynamic range of action. Resistance between 1,3 feet Ri, Rin and capacitor C1 constitute a pre-emphasis network. The output end of the resistor Rflash cathode discharge protection, when a high voltage discharge, serves to limit the current and voltage limiting effect. Vcc (6 feet), VDD (10 feet) must be added decoupling capacitors, high-frequency decoupling capacitance characteristics of a good ceramic capacitors and electrolytic capacitors connected in parallel.
