AN5275

Overview

The AN5275 is a dual-channel low-frequency power amplifier IC designed for TV sound output applications, delivering 15W per channel. It operates within a supply voltage range of 10V to 40V and utilizes a 12-lead HSIP package. The device features a typical static circuit current of 32mA and a ripple rejection ratio of 45dB at 120Hz. Total harmonic distortion is specified at 0.4% under standard test conditions.

Feature Summary

• Integrated audio muting function with minimal shock noise during power transitions
• Comprehensive protection circuits including load short-circuit, overvoltage, overcurrent, and thermal safeguards
• Eliminates the need for bootstrap electrolytic capacitors, reducing external component count

Applications

• TV sound output systems
• Dual-channel stereo audio amplification
• Low-frequency power amplifier circuits

Procurement Notes

Verify the specific package type and manufacturer revision before procurement. Confirm that the application environment remains within the absolute maximum ratings, particularly regarding peak supply voltage and power dissipation limits. Ensure proper heat sinking is implemented if operating near maximum power thresholds to maintain reliability.

Selection Notes

Select this component for designs requiring high-density mounting and reduced external parts. It is suitable for general electronic equipment where low distortion and built-in protections are necessary. Verify compatibility with the target supply voltage range and ensure adequate thermal management solutions are integrated into the PCB layout.

Part Context

This part belongs to Panasonic's series of ICs for common audio use. It is engineered for cost reduction through fewer external components while maintaining high reliability. The design supports standard applications such as household appliances and office equipment, distinct from specialized aerospace or life-support systems.

Replacement Considerations

Datasheet documentation indicates compatibility with the AN5275 and AN5276 models. Verify pinout and electrical specifications against these references before substitution.
