This eliminates the need for an input coupling capacitor. However, in case the brush noise of volume becomes a problem, provide serially a coupling capacitor to the input side. (2) Adjustment of voltage gain The voltage gain is fixed at Gy=56.5dB by the resistors (Ry and R92) in IC, however, its reduction is possible through adding Rf as shown in Fig.1. In this case, the voltage gain is obtained by the following equation. R1+R2+R Gy=20f0g Ry, +R It is recommended to use this IC with the voltage gain of G,y=40dB or over. (3) Measures against oscillation For the capacitors Cg and C7 to be applied for preventing the oscillation between output terminal and GND, use the polyester film capacitor having superior quality in high frequency and temperature characteristics, however, since the characteristics of the capacitor may be different depending on the manufactures or kinds, apply the capacitor after confirmation. Since the characteristics of the capacitor of the ceramic Type are liable to be affected by the temperature and the voltage, use the capacitor of larger capacity and be sure to perform the thermal test to check the oscillation allowance.
