an Guan ! ' 30k + PROTECTION CIRCUIT G)— a= our poor pet $4 I ' BS2 30k Pre-GND APPLICATION INFORMATION AND APPLICATION METHOD 1. Adjustment of voltage gain The voltage gain Gy is obtained as follows by R1, R2 and R¢ in Fig.1 input Gy = 20f0g Re zn a R2 Oo OUTPUT Re en) When R¢=00 Gy = 56.5dB (Typ.) cue “HE Gs) am When Rf = 1200 Gy = 45dB (Typ.) ‘ls By increasing Rf, reduction of Gy is possible. However, . since the feedback increase is liable to produce Fig.1 oscillation, 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. 1999-03-05 2/10

Input stage The input circuit of this IC is as shown in Fig.2. PNP Ty : Q1 is provided in the input circuit so as oO ® output to make its usage possible without the input 30kQ. Gin) However, at pin® and @, max 60mvV offset ll (17) oN Ob @ voltage is produced. 3 S Application after checking volume slide noise is (+) < recommended. For cutting the volume slide noise, insert the (9) input capacitor : Cj in series to interrupt the Re DC component. “be 4. Oscillation preventive measures be For oscillation preventive capacitor Cg and C7 Fig.2 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 by 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 Cig 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 checking 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 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 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 = 300 MVrms (Typ.) : Vcc = 9V, RL = 40, f = 1kHz : Enough care must be taken for this phenomenon. 1999-03-05 3/10
