• Manufacturer Part Number: la4265
• Description: 3.5w Monaural Power Amplifier
• Manufacturer: Sanyo Semiconductor Corporation

• Printed circuit pattern
• Some plug jacks to be used for connecting to the external speaker can have the both poles short-circuited once when
When designing the printed circuit pattern, make the power supply, output, and ground lines thick and short and
arrange the pattern and parts so that no feedback loop is formed between input and output. Place power capacitor C5,
oscillation blocking capacitor C3 as close to IC pins as possible to prevent oscillation from occurring. Refer to the
sample printed circuit pattern.
connecting. In this case, the load is short-circuited, which may break down the IC.

the customer should always evaluate and test devices mounted in the customer's products or equipment.
SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all
semiconductor products fail with some probability. It is possible that these probabilistic failures could
give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire,
or that could cause damage to other property. When designing equipment, adopt safety measures so
that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective
circuits and error prevention circuits for safe design, redundant design, and structural design.
