Precaution For Use And Application 1. Input stage The input stage of power amplifier (equivalent circuit) is comprised of a PNP differential pair (Q 2 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 becomes a problem, provide serially a coupling capacitor to the input side. 2. Adjustment of voltage gain The voltage gain is fixed at G V≒40dB 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 equation. fR 4R fR 4R 5R og20 VG /G2b /G2b/G2b/G3d/G6c It is recommended to use this IC with the voltage gain of GV = 28dB or over. 3. Ripple rejection ratio Adding C RIP, to ripple terminal 2 as shown in Figure 3, the ripple rejection ratio is improved from /G2d25d/G42 typ. to /G2d45d/G42 typ. 4. Power dissipation Care should be taken to use this IC below maximum power dissipation. Because it may over maximum rating depending on operating condition. /Gb7/G20TA7368P P D = 900mW (Ta = 25°C) /Gb7/G20TA7368F P D = 400mW (Ta = 25°C) 5.
