DC muting To apply DC muting by controlling the NF pin, it is recommended to use the circuit configuration shown right. In this circuit LA ratasheet wired in bridge mode.
LA (Sanyo) – 2-channel Af Power Amp For Radio, Tape Recorder Use | eet
However, if slider contact noise of the variable resistor presents any problem, connect a. For AC power supply, however, it datashet recommended to actually measure Pd on the transformer of each.
Power dissipation Pd is increased depending on the supply voltage and load. For stereo application, two identical amplifier modes have to be datashfet according to the circuit diagram. So, be careful of the transformer regulation. Capacitors C1 and C7 are meant for bootstrapping. The material of the. If the transformer regulation is not as specified, the supply voltage drops momentarily when the motor of an AC. Branch C2, R1 and C8, R3 are meant for preventing oscillations, and so the high frequency stability of the LA audio amplifier gets improved.
It is recommended to apply silicone grease to the IC. Supply voltage at maximum output. So, it is recom- mended la45550 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.

Example of Heat Sink Mounting Method. 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 datasheeet other parameters lla4550 in products specifications of any and all SANYO products described or contained herein. Supply voltage at maximum output r: The following is a formula to be used to calculate Pd.
Supply voltage at Pd max. Leave a Reply Cancel reply Your la45500 address will not be published. To apply DC muting by controlling the NF pin, it is recommended. The LA can be operated from 12 Vdc and can deliver 4W of output power into an 8 ohm speaker. In this case, hum noise may be generated. Previous post Next post.
Capacitors Dqtasheet and C10 are meant for coupling the speaker to the IC. Since the input circuit uses PNP transistors, no input coupling capacitor is required.
The following is a formula to be used to calculate Pd for stereo use. Cu-foiled area in the vicinity of the heat sink of the IC as large as possible when designing the printed circuit board. Slider contact noise of variable resistor Since the input circuit uses PNP transistors, no input coupling capacitor is required. Supply voltage at quiescent mode V CC Pd: You may also like: In the circuit capacitors La45550 and C3 provides feedback and their value datashedt the lower cut-off frequency.
Audio input can be applied laa4550 pin 8 of the IC with respect to the ground. If the transformer regulation is not as specified, the supply voltage drops momentarily when the motor of an AC- powered set is turned ON.
