LA4550 SPC, सर्किट, समारोह
In this case, hum noise may be generated. 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.
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 plastic area to reduce thermal resistance between the heat sink and the IC plastic area.
LA datasheet & applicatoin notes – Datasheet Archive
Audio input can be applied to pin 8 of the IC with respect to the ground. The material of the heat sink is recommended to be copper or iron which is solderable. Your email address will not be published.
If the transformer regulation is not as specified, the darasheet voltage drops momentarily when the motor of an AC- powered set is turned ON. Supply datasheey at quiescent mode. 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.
The heat sink must be of such a shape as to be able to dtasheet heat from the IC plastic area and fin area and is soldered to. You may also like: It is recommended to apply silicone grease to the IC. Slider contact noise of variable resistor Since the input circuit uses PNP transistors, no input coupling capacitor is required. Supply voltage at maximum output r: Supply voltage at maximum output. Since the input circuit uses PNP transistors, no input coupling capacitor is required. For stereo application, two identical amplifier modes have to be built according to the circuit diagram.
SANYO assumes no responsibility for equipment failures that result from lw4550 products at values that exceed, even momentarily, rated values such as maximum ratings, operating condition ranges,or other parameters listed in products specifications of any and all SANYO products described or contained herein.
For the size of the heat sink, refer to the Pd — Ta characteristic. So, it is recom- mended to use the printed circuit board together with the heat sink. LA is a 2 channel audio frequency power amplifier IC specifically designed for radio, tape-recorder use etc.
AUDIO Cross Reference LA4550
The LA can be operated from 12 Vdc and can deliver 4W of output power into an 8 ohm speaker. Supply voltage at quiescent mode V CC Pd: C4 is a ripple filtering capacitor while C11 and C12 are meant for power supply filtering.
If the transformer regulation is not as specified, the supply voltage drops momentarily when the motor of an AC. DC muting To apply DC muting by controlling the NF pin, it is recommended to use the circuit configuration shown right.
LA audio amplifier circuit.
For AC power supply, however, it is recommended to actually measure Pd on the transformer of each. Supply voltage at Pd max V CC 1: For AC power supply, however, it is recommended to actually measure Pd on the transformer of each set. Capacitors C9 and C10 are meant for coupling the speaker to the IC. In this circuit LA dataheet wired in bridge mode. So, be careful of the transformer regulation.
The material of the. SANYO assumes no responsibility for equipment failures that result from using products datwsheet values that. However, if slider contact noise of the variable resistor presents any problem, connect a.
Example of Heat Sink Mounting Method.
Power dissipation Pd is increased depending on the supply voltage and load.
