Since the input circuit uses PNP transistors, no input coupling capacitor is required.
Slider contact noise of variable resistor. For AC power supply, however, it is recommended to actually measure Pd on the transformer of each.
In this circuit LA is wired in bridge mode. DC muting To apply DC muting by controlling the NF pin, it is recommended to use the circuit configuration shown right. The material of the.
Slider contact noise of variable resistor 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. In the circuit capacitors C6 and C3 provides feedback and their value determines the lower cut-off frequency.
You may also like: So, be careful of the transformer regulation. The potential at point. SANYO assumes no responsibility for equipment failures that result from datashete 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.
SANYO assumes no responsibility for equipment failures that result from using products at values that.
So, it is recom- mended to use the printed circuit board together with the heat sink. Cu-foiled area in the vicinity of the datashheet sink of the IC as large as possible when designing the printed circuit board. Supply voltage at Pd max V CC 1: 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.

The material of the heat sink is recommended to be copper or iron daatsheet is solderable. If the transformer regulation is not as specified, the supply voltage drops momentarily when the motor of an AC- powered set is turned ON.
C4 is a ripple filtering capacitor while C11 and C12 are meant for power supply filtering. Leave a Reply Cancel reply Your email address will not be published. The LA can be operated from 12 Vdc and can deliver 4W of output datasehet into an 8 ohm speaker.
Since the DIPF package is such that the Cu-foiled area of the printed circuit board is used to dissipate heat, make the. The following is a formula to be used to calculate Pd for stereo use. Supply voltage at quiescent mode.

Supply voltage at Pd max. However, if slider contact noise of the variable resistor presents any problem, connect a capacitor in series with input. Example of Heat Sink Mounting Method.
Audio dataeheet can be applied to pin 8 of the IC with respect datzsheet the ground. Supply voltage at maximum output. The following is a formula to be used to calculate Pd. In this case, hum noise may be generated. 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. 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.
If the transformer regulation is not as specified, the supply voltage drops momentarily when the motor of an AC.
Supply voltage at quiescent mode V CC Pd: Capacitors C9 and C10 are meant for coupling the speaker to the IC. Capacitors C1 and C7 are meant for bootstrapping.
It is recommended to apply silicone grease to the IC.
