O TOSHIBA is continually working to improve the quality and the reliability of its products. Nevertheless, semiconductor devices in general can
malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical stress. It is the responsibility of the buyer, when utilizing
TOSHIBA products, to observe standards of safety, and to avoid situations in which a malfunction or failure of a TOSHIBA product could cause loss
of human life, bodily injury or damage to property. In developing your designs, please ensure that TOSHIBA products are used within specified
operating ranges as set forth in the most recent products specifications Also, please keep in mind the precautions and conditions set forth in the
TOSHIBA Semiconductor Reliability Handbook.

TOSHIBA TA7368P/F
PRECAUTION FOR USE AND APPLICATION
1. Input stage C) : TA7368P/TA7368F
The input stage of power amplifier (Equivalent circuit) is
comprised 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
becomes a problem, provide serially a coupling capacitor to the
input side.
2. Adjustment of voltage gain
The voltage gain is fixed at GV'=.4OdB 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.
R +R +R
GV = 20tog 5+”
R4 + Rf
It is recommended to use this IC with the voltage gain of
GV=28dB or over.

3. Ripple rejection ratio +
CRIP I
Adding CRIP, to ripple terminal 2 as shown in Figure 3, the
ripple rejection ratio is improved from -25dB Typ. to -45dB Fig.3
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.
o TA7368P PD=900mW (Ta=25°C)
o TA7368F PD=400mW (Ta=25°C)
5. Phase-compensation
Small temperature coefficient and excellent frequency characteristic is needed by capacitors below.
It Oscillation preventing capacitors for power amplifier output
0 Bypass capacitor for ripple filter
It Capacitor between VCC and GND
