Supply voltage at quiescent mode. The following is a formula to be used to calculate Pd.
LA4550 SPC, सर्किट, समारोह
So, be careful of the transformer regulation. In the circuit capacitors C6 and C3 provides feedback and their value determines the lower cut-off frequency.
It is recommended to apply silicone grease to the IC. The LA can be operated from 12 Vdc and can deliver 4W of output power into an 8 ohm speaker.

The potential at point. For stereo application, two identical amplifier modes have to be built according to the circuit diagram. So, it is recom- mended to use the printed circuit board together with the dwtasheet sink.

The use of the Cu-foiled area indicated by shading in the above-mentioned sample printed circuit pattern makes it possible to dissipate more heat. Cu-foiled area in the vicinity of the heat sink of the IC as large as possible when designing the printed circuit board.
Power dissipation Pd is increased depending on the supply voltage and load.
If the transformer regulation is not as specified, the supply voltage drops momentarily when the motor of an AC- powered set is turned ON. Slider contact noise of variable resistor Since the input circuit uses Lq4550 transistors, no input coupling capacitor is required. Since the DIPF package is such that the Cu-foiled area of the printed circuit board is used to dissipate heat, make the.
Capacitors C9 and C10 are meant for coupling the speaker to the IC.
However, if slider contact noise of the variable resistor presents any problem, connect a capacitor in series with input. The following is a formula to be used to calculate Pd for stereo use. DC muting To apply DC muting by controlling the NF pin, it is recommended to use the circuit configuration shown right.
Supply voltage at maximum output. For AC power supply, however, it is recommended to actually measure Pd on the transformer of each set. So, it is recom.
Supply voltage at Pd max. Slider contact noise of variable resistor. The heat sink must be of such a shape as to be able to dissipate heat from the IC plastic area and fin area and is soldered to. To apply DC muting by controlling the NF pin, it is recommended.
In this circuit LA is wired in bridge mode. Previous post Next post. LA audio amplifier circuit.

Supply voltage at Pd max V CC 1: Capacitors C1 and C7 are meant for bootstrapping. However, if slider contact noise of the variable resistor presents any problem, connect a. Thermal Design Since the DIPF package is such that the Cu-foiled area of the printed circuit board is used to dissipate heat, make the Cu-foiled area in the vicinity of the heat sink of the IC as large as possible when designing the printed circuit board.
For the size of the heat sink, refer to the Pd — Ta characteristic. Since the input circuit datassheet PNP transistors, no input coupling capacitor is required.
