Adjustment of voltage gain The voltage gain GV is obtained as follows by R1, R2 and Rf in Fig.1. Rf + R1 + R2 GV = 20 log Rf + R1 When Rf = 0Ω, GV = 56.5dB (Typ.) When Rf = 120Ω, GV = 45dB (Typ.) By increasing Rf, reduction of GV is possible. However, since the feedback increase is liable to produce oscillation, it is recommended to use this at 40dB or over.

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℃(Typ.). At this temperature or over the bias is interrupted to prevent the destruction of IC. UTC UNISONIC TECHNOLOGIES CO., LTD. 3 QW-R107-028,A UTC TA8229 LINEAR INTEGRATED CIRCUIT 3. Input stage The input circuit of this IC is as shown in Fig.2. PNP Tr: Q1 is provided in the input circuit so as to make its usage possible without the input coupling capacitor. However, at pin 11 and 12 , max 60 mV offset voltage is produced. Application after checking volume slide noise is recommended. For cutting the volume slide noise, insert the input capacitor: CIN in series to interrupt the DC component.

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 gin 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 ⑧pin. However, output power is changed by ⑧pin supply voltage when ⑧pin supply voltage is not same ④pin supply voltage, after referring to attached date, select ⑧pin 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.): VCC = 9V, RL = 4Ω, f = 1kHz: Enough care must be taken for this phenomenon.
