Audio input can be applied to 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. In the circuit capacitors C6 and C3 provides feedback and their value determines the lower cut-off frequency. Previous post Next post. Example of Heat Sink Mounting Method.
The following is a formula to be used to calculate Pd for stereo use. The LA can be operated from 12 Vdc and can deliver 4W of output power into an 8 ohm speaker. Capacitors C9 and C10 are meant for coupling the dataeheet to the IC.
For AC ratasheet supply, however, it is recommended to actually measure Pd on the transformer of each. Capacitors C1 and C7 are meant for bootstrapping. Since the input circuit uses PNP transistors, no input coupling capacitor is required.
Supply voltage at maximum output. If the transformer regulation is not as specified, the supply voltage drops momentarily when the motor of an AC. SANYO assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated la450 such as maximum ratings, operating condition ranges,or other parameters listed in products specifications of any and all SANYO products described or contained herein.
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 material of the.

To apply DC muting by controlling the NF pin, it is recommended. Cu-foiled area in the vicinity of the heat sink of the IC as large as possible when designing the printed circuit board. The following is a formula to be used to calculate Datsheet. Supply voltage at Pd max.
LA audio amplifier circuit. SANYO assumes no responsibility for equipment failures that result datashet using products at values that. For AC power supply, however, it is recommended to actually measure Pd on the transformer of each set.
For stereo application, two identical amplifier modes have to be built according to the circuit diagram. So, it is recom. Slider contact noise of variable resistor. Supply voltage at Pd max V CC 1: Supply voltage at maximum output r: Branch C2, R1 and C8, R3 are meant for preventing oscillations, and so the high frequency stability of the LA audio amplifier gets improved.
Since the DIPF package is such that the Cu-foiled area of the printed circuit board is used to dissipate heat, make the. So, it is recom- mended to use the printed circuit board together with the heat sink. Dxtasheet potential at point A is set to 3.
The potential at point. Supply voltage daasheet quiescent mode V CC Pd: C4 is a ripple filtering capacitor while C11 and C12 are meant for power supply filtering.
LA is a 2 channel audio frequency power amplifier IC specifically designed for radio, tape-recorder use etc. For the size of the heat sink, refer to the Pd — Ta characteristic.
