• Includes built-in volume control circuitry
• Employs balanced transformerless (BTL) architecture

Applications

• Televisions
• Audio equipment
• Personal computers
• Active speakers

Procurement Notes

Verify current lifecycle status as the product is listed under maintenance or discontinued categories. Confirm availability through official Panasonic Industry channels or authorized distributors. Ensure compliance with export regulations if applicable. Review the latest product standards before finalizing design implementation.

Selection Notes

Select this component for stereo systems requiring integrated volume and standby controls. Consider thermal dissipation requirements when operating at high supply voltages. Verify compatibility with 8 Ω loads for optimal performance. Ensure proper grounding connections for heat sinks to maintain safe operating temperatures.

Part Context

This part belongs to Panasonic's line of audio power amplifier integrated circuits designed for consumer electronics. It is specifically engineered for stereo applications where reduced external parts count is beneficial. The BTL configuration allows for higher output power compared to single-ended designs within similar voltage constraints.

Replacement Considerations

Consult Panasonic Industry documentation for verified substitute part numbers. Check for updated specifications in newer generations of audio amplifiers. Ensure pinout and electrical characteristics match existing designs before substitution.
