Input stage The input stage of power amplifier (equivalent circuit) is prised of a PNP differential pair (Q2 and Q3) preceded by a PNP emitter follower (Q1) which allows DC referencing of the source signal to ground. This eliminated the need for an input coupling capacitor. However, in case the brush noise of volume bees a problem, provide serially a coupling capacitor to the input side. / : TA7368P / TA7368F 9/2 Q2 Q3 FROM PIN 7 / 10 R5 R1 27kΩ R4 2. Adjustment of voltage gain The voltage gain is fixed at GV≒40d B by the resistors (R4 and R5) in IC, however, its reduction is possible through adding Rf as shown in Figure 2. In this case, the voltage gain is obtained by the following...
