For AC power supply, however, it is recommended to actually measure Pd on the transformer of each set. Audio input can be applied to pin 8 of the IC with respect to the ground. Capacitors C9 and C10 are meant for coupling the speaker to the IC. 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.
For the size of the heat sink, refer to the Pd — Ta characteristic. SANYO assumes no responsibility for equipment failures that result from using products at values that. In this case, hum noise may be generated. LA is a 2 channel audio frequency power amplifier IC specifically designed for oa4550, tape-recorder use etc.
Since the DIPF package is such that the Cu-foiled area of the printed circuit board is used to dissipate heat, make the.
So, be careful of the transformer regulation. Supply voltage at Pd max V CC 1: Supply voltage at quiescent mode. It is recommended to apply silicone grease to the IC. Branch C2, R1 and C8, R3 are meant for preventing oscillations, and so the high frequency stability of the LA audio amplifier gets improved. Slider contact noise of variable resistor. For stereo application, two identical amplifier modes have to be built according to the circuit diagram.
Supply voltage at maximum output r: Cu-foiled area in the vicinity ka4550 the heat sink of datashest IC as large as possible when designing the printed circuit board.
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. Supply voltage at Pd max. The following is datasgeet formula to be used to calculate Pd for stereo use.
Your email address will not be published. So, it is recom- mended to use the printed circuit board together with the heat sink.
Supply voltage at quiescent mode V CC Pd: In the circuit capacitors C6 and C3 provides feedback and their value determines the lower cut-off frequency. In this circuit LA is wired in bridge mode. Power dissipation Pd is increased depending on the supply voltage and load. LA audio amplifier circuit. Since the input circuit uses Datashret transistors, no input coupling capacitor is required.

Supply voltage at maximum output. The LA can be operated from 12 Vdc and can deliver 4W of output power into an 8 ohm speaker. The heat sink must be of such a shape as datasheet be able to dissipate heat from the IC plastic area and fin area and is soldered to. For AC power supply, however, it is recommended to actually measure Pd on the transformer of each.
However, if slider datadheet noise of the variable resistor presents any problem, connect a capacitor in series with input. Thermal Design Since the DIPF package is datsaheet 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. SANYO assumes no responsibility for equipment failures that result from using products at datssheet 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.
If the transformer regulation is not as specified, the supply voltage drops momentarily when the motor of an AC.

The material of the. Example of Heat La45550 Mounting Method. To apply DC muting by controlling the NF pin, it is recommended. Previous post Next post.
C4 is a ripple filtering capacitor while C11 and C12 are meant for power supply filtering. The material of the heat sink is recommended to be copper or iron which is solderable. Capacitors C1 and C7 are meant for bootstrapping.
The following is a formula to be used to calculate Pd. Leave a Reply Cancel reply Your email address will not be published. You may also like: If the transformer regulation is not as specified, the supply voltage drops momentarily when the motor of an AC- xatasheet set is turned ON.
