4 / 9 page Sample Print Pattern Description of External Components C1, C4 Input capacitors 2.2 µF is recommended. fL can be varied by C1, C4 capacitances to adjust the bass range. C2 Decoupling capacitor (ripple filter) C3 Amplifier on time setting capacitor Approximately 0.8 second for 33 µF. Since the on time is proportional to this capacitance, it can be set as desired by varying this capacitance. (Refer to the characteristics curve.) C5 Power supply capacitor C6, C7, C8, C9 Oscillation blocking capacitors Use polyester film capacitors (Mylar capacitors) with good temperature characteristics. (R2, R3, R4, and R5 used jointly.) Since stability may be affected slightly by the pattern layout, etc., 0.1 µF or more is recommended. R1 Standby switch current limiting resistor 10 k Ω is recommended (when the applied voltage for the standby switch is 2.5 V to 13.2 V). This resistor cannot be removed. Copper foil area 90 × 105 mm2 LA4708 No.5245 -4/9 |
