Internal circuit structure of STKS0100

ST K0100 thick film hybrid integrated circuit is an OCL type power amplifier output circuit that uses dual power supplies . Its characteristics
are good temperature stability, the quiescent current has temperature compensation characteristics, the gain of the circuit can be adjusted through the settings of the external circuit
, and the degree of freedom is high. The package has good heat dissipation and is easy to use. The
    internal circuit structure of srKOl00 is shown in Figure 295. As can be seen from the figure, it is equivalent to the power output part of a typical OCL power amplifier circuit
. The circuit is very simple, consisting of only 5 transistors, 2 diodes and 5 resistors. oVTi and 1Ⅵ, Ⅵ≥, Rl,
R2 have temperature Output stage static bias circuit with compensation function, VT2 ~ VTs form a composite fully complementary push-pull output stage port
