Figure Input coupling capacitor (Cin) input coupling capacitor, used cutting. However, this capacitor also used improve ripple rejection ratio, which changes according capacitance value (recommended value 1µF). addition, this capacitor also affects transient response characteristics during power-on when mute canceled, constant should consideration these characteristics. Design reference value approximately 0.33 3.3µF Ripple rejection ratio Increasing capacitance value increases rate, reducing value reduces rate. Rise response speed Increasing capacitance value reduces speed, reducing value increases speed. Popping noise Increasing capacitance value reduces noise, reducing value increases noise. Output coupling capacitor (Cout) Cout output coupling capacitor used cutting. However, this capacitor, Cout, combination with load impedance forms high-pass filter attenuates frequency signal. Take into account cutoff frequency when determining capacitance value. addition, normally chemical capacitor used this capacitor, capacitance value chemical capacitors decreases temperatures, value should accordance with this characteristic. cutoff frequency expressed following formula. 1/(2 Cout) Output phase compensation capacitor (Cosc) Cosc capacitor used prevent output oscillation. ceramic capacitor (recommended value 0.1µF) with good high frequency characteristics, locate this capacitor close possible. Power supply capacitor (CVCC) CVCC capacitor used suppress ripple component power supply line. Normally chemical capacitor (recommended value 10µF) used this capacitor. However, chemical capacitors have poor high frequency characteristics, when using CPU, other that generates digital noise set, recommended that power supply bypass capacitor (ceramic capacitor, recommended value approximately 0.1µF) added reject high-frequency components. Locate this bypass capacitor close possible.

Short-circuit between pins Turning power supply with some pins short-circuited cause deterioration breakdown. Therefore, when mounting board, check make sure that short-circuit formed between pins solder other foreign substances before turning power supply. Load short circuit Leaving long time condition with load short circuit cause deterioration breakdown. Therefore, never short-circuit load. Maximum ratings When used under conditions near maximum ratings, even slight fluctuation conditions cause maximum ratings exceeded, possibly resulting breakdown other accidents. Therefore, always provide enough margin fluctuations supply voltage other conditions, within range exceeding maximum ratings.
