Adjustment of voltage gain The voltage gain Gy is obtained as follows by R1, R2 and R in Fig.1. R Ri + R2 Gy = 20 fog Et NIE NS OUTPUT Rf + R1 When Rf = 00, Gy = 56.5 dB (Typ.) When Rt = 1200), Gy = 45dB (Typ.) CNF f By increasing R, reduction of Gy is possible. However, since the feedback increase is liable to produce oscillation, it is recommended to use this at Ant ( Fig.1) 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 175C (Typ.). At this temperature or over the bias is interrupted to prevent the destruction of IC. 3. Input stage The input circuit of this IC is as shown in Fig.2. OUTPUT PNP Tr : Q1 is provided in the input circuit so as to make its usage possible 02 08 30kQ @ without the input coupling capacitor. However, at pin@) and , max 60 mV To DRIVER offset voltage is produced. oO Ss Application after checking volume slide ~ noise is recommended. NE To Bias For cutting the volume slide noise, fo, insert the input capacitor : Cinq in r r TN series to interrupt the DC component. ( Fig.2] 3 2001-06-25TOSHIBA TA8229K 4. Oscillation preventive measures For oscillation preventive capacitor C6 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 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 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 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.
