Kagajar However, if slider contact noise of the variable resistor presents any problem, connect a capacitor in series with input. In this circuit LA is wired in bridge mode. For stereo application, two identical amplifier modes have to be built according to the circuit diagram. 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.

However, if slider contact noise of the variable resistor presents any problem, connect a. So, it is recom. It is recommended to apply silicone grease to the IC. If the transformer regulation is not as al, the supply voltage drops momentarily when the motor of an AC- powered set is turned ON. Supply voltage at maximum output.

So, be careful of the transformer regulation. Slider contact dataeheet of variable resistor. LA is a 2 channel audio frequency power amplifier IC specifically designed for radio, tape-recorder use etc. SANYO assumes no responsibility for equipment failures that result from using 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 datashewt all SANYO products described or contained herein.

The material of the. 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.

Capacitors C1 and C7 are meant for bootstrapping. Example of Heat Sink Mounting Method. C4 is a ripple filtering capacitor while C11 and C12 are meant for power supply filtering. The LA can be operated from 12 Vdc and can deliver 4W of output power into an 8 ohm speaker.

So, it is recom- mended to use the printed circuit datqsheet together with the heat sink. The material of the heat sink is recommended to be copper or iron which is solderable.

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. Capacitors C9 and C10 are meant for coupling the speaker to the IC.

The potential at point A is set to 3. To apply DC muting by controlling the NF pin, it is recommended. Slider contact noise of variable resistor Since the input circuit uses PNP transistors, no input coupling capacitor is required. LA audio amplifier circuit 4W, 8 ohm, 12V operation In this case, hum noise may be generated.

Since the input circuit uses PNP transistors, no input coupling capacitor is required. DC muting To apply DC muting by controlling the NF pin, it is recommended to use the circuit configuration shown right. The following is a formula to be used to calculate Pd. For AC power supply, however, it is recommended to actually measure Pd on the transformer of each set.

Supply voltage at Pd max. Thermal Design Since the Datxsheet package is such that the Cu-foiled area of the printed circuit board is used to dissipate heat, make the Daatasheet area in the vicinity of the heat sink of the IC as large as possible when designing the printed circuit board.

Audio input can be applied to pin 8 of the IC with respect to the ground. LA audio amplifier circuit. 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.

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. For AC power supply, however, it is recommended to actually measure Pd on the transformer of each. Your email address will not be published.
