APPLICATION INFORMATION
1.VOLTAGE GAIN ADJUSTMENT
(1) DUAL AMPLIFIER
The voltage gain Gv is determined by Ri, R2 and Rt in Fig. 1.
G^ y = 20 log

It is recommended to use the capacitor having the capacity exceeding the
oscillation stopping value.
At using with the voltage gain Gv lowered or with the high range frequency and the
oscillation becomes liable to be produced.
Therefore, application with Gv=40dB or over is advisable.
Especially for using with the gain lowered in DUAL operation, insert lOOOpF
between NF (9 pin and 11 pin) and GND.
This capacitor reduces the gain of the high range frequency and is effective for
oscillation prevention.
4. OUTPUT WAVEFORM AT POWER SUPPLY ON/OFF
BTL and dual Amplifier DC output waveforms in the condition of Vcc=13.2V,
Rl=4£2 at non-signal (input short) are shown in Fig. 5 and 6.
