UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 6 of 9 QW-R107-033.C UA8229 LINEAR INTEGRATED CIRCUIT APPLICATION INFORMATION 1. Adjustment of voltage gain The voltage gain GV is obtained by R1, R2 and RF as below. By increasing RF, reduction of GV is possible. 40dB or over in use is recommended. RF + R1 + R2 GV = 20 log RF+ R1 Sine oscillation is probable as a result of feedback in crease. 2. Input stage The input circuit of this IC is as shown as below. PNP TR: TR1 is provided in the input circuit so as to make its usage possible without the input coupling capacitor. However, at Pin 10 and Pin 11 max 60 mV offset voltage is produced. Fig.2 illustrate the input circuit of UTC UA8229. A offset voltage of 60mV max is possible. TR1 is featured to eliminate the usage of coupling capacitor.

Input voltage When the excessive signal is input, turning-up is produced in the clip waveform. 4. Oscillation preventive measures Mylar capacitor in use is strongly recommended to fulfill well handled of oscillation temperature and high frequency. 5. Power ON/OFF switch There is power ON/OFF switch at Pin 7(HZIP-15A’s Pin 8). However, output power is changed by Pin 7(HZIP-15A’s Pin8) supply voltage when Pin 7(HZIP-15A’s Pin 8) supply voltage is not same Pin 3(HZIP-15A’s Pin 4) supply voltage, after referring to attached date, select Pin 7 (HZIP-15A’s Pin 8)supply voltage. 6. Thermal shut-down Protection The thermal shut-down circuit is built-in to dodge IC damage that result from the abnormal temperature rise during operating.
