Sample Application Circuit 1 : Speaker load
Sample printed circuit pattern (Cu-foiled area)
Description of external parts
C1 (1
μF)
: Input capacitor (Coupling capacitor for input signal)
Decreasing the capacitance value lowers the frequency response at low frequencies.
C2 (22
μF)
: Feedback capacitor (Bypass of feedback signal)
Decreasing the capacitance value lowers the frequency response at low frequencies ; increasing the
capacitance value makes the starting time later.
C3 (4.7
μF)
: Muting capacitor
Decreasing the capacitance value makes the starting time earlier ; removing C3 causes pop noise.
Increasing the capacitance value makes the starting time later.
C4 (220pF)
: Phase compensation capacitor (Phase compensation by local feedback) Decreasing the capacitance
value causes the frequency response to extend at high frequencies, and thereby oscillation is liable to
occur. Increasing the capacitance value worsens distortion factor at high frequencies.
C5 (0.47
μF) : Oscillation blocking capacitor
Decreasing the capacitance value causes oscillation to liable to occur. Using an ordinary electrolytic
capacitor may cause oscillation to occur at a low temperature. Use a tantalum or alsicon electrolytic
capacitor that is good in temperature characteristic.
C6 (470
μF) : Output capacitor (Cutoff of DC to speaker)
Decreasing the capacitance value causes insufficient power at low frequencies.
C7 (220
μF) : Bootstrap capacitor (Feedback from output stage)
Decreasing the capacitance value causes insufficient power at low frequencies, especially when
voltage is reduced.
C8 (220
μF) : Power capacitor (Drop in power impedance)
Decreasing the capacitance value causes motor noise, etc. to be entered easily. Removing C8 may
cause oscillation to occur.
C9 (47
μF)
: Capacitor for ripple filter (Filter for bias voltage)
Decreasing the capacitance value causes the circuit to be subjected to the influence of power supply,
and thereby ripple is liable to occur.
ri (100Ω)
: Feedback resistor (Setting of voltage gain)
Decreasing the resistance value increases voltage gain, but worsens distortion factor, and thereby gain
varies. Increasing the resistance value causes oscillation to liable to occur.
