ADJUSTMENT OF VOLTAGE GAIN The voltage gain Gy is obtained as INPUT follows by R1, R2 and Rg in Fig. 1. (%) > ® oy=20¢0, —BEHBI#RA ) ae ounsvr st] & When R¢=0 Gy=56dB(Typ.) omy When R¢=820 Gy=45dB (Typ.) By increasing Rf, reduction of Gy is possible. However, since the feedback increase is liable to produce oscillation, Fig. 1 it is recommended to use this at 40dB or over. 2, THERMAL SHUT-DOWN CIRCUIT . The thermal shut-down circuit is built in for the purpose of preventing the destruction of IC due to the abnormal temperature rise when the heat radiation is insufficient. The operation temperature is set at radiation Fin temperature 175°C(Typ.). At this temperature or over the bias is interrupted to prevent the destruction : of IC. 3.

For cutting the volume slide noise, insert the input capacitor:Cin in series to interrupt the DC compornent. 4. OSCILLATION PREVENTIVE MEASURES For oscillation preventive capacitor Cg and C7 between the output terminal and GND, it is recommended to use polyester film capacitor having good characteristics for temperature and for high frequency. Since the characteristics of the capacitor is liable to be influenced the temperature, use this capacitor after the temperature test to check the oscillation allowance. In addition, as the position of the electrolytic capacitor has a remarkable influence on the oscillation, connect C10 to Vcc at the nearest possible position from power GND. At using this application with the voltage gain reduced, oscillation is liable . ‘to be produced. Apply the capacitor after cheking enough for its capacity, type and mounting position. * As the oscillation allowance varies according to the printed pattern layout, . the standard printed board of TOSHIBA is recommended to be referred to for design it. 5. POWER ON/OFF SWITCH There is power ON/OFF switch at @pin. However, output power is changed by ©pin supply voltage when @pin supply voltage is not same (12) pin supply voltage, after referring to attached date, select @ pin supply voltage. 6. INPUT VOLTAGE When the excessive signal is input, turning-up is produced in the clip waveform. The turning-up point is Vin=300mVrms(Typ.):Voc=9V, RL=40, f=1kHz:Enough care must be taken for this phenomenon. { 7. GND LINE GND pin is not separated for Pre-GND and for Py-CND. ‘That is liable to cause i distortion and cross talk worse. Before use this IC, please chack it. ‘eee sec eee ee AUDIO LINEAR I1C== —187- This Material Copyrighted By Its Respective Manufacturer
