AN5276

Overview

The AN5276 is a monolithic dual-channel SEPP audio power amplifier IC designed for stereo TV applications. It delivers 5.0 W output at 19 V into an 8 Ω load, with a maximum of 5.6 W at 22 V (THD=10%). The operating voltage range spans 10 V to 24 V. Key electrical characteristics include a quiescent current of 35–70 mA, voltage gain of 32–36 dB, and total harmonic distortion of 0.2–0.4%. It features high ripple rejection of 55 dB and built-in protection circuits for thermal, over-voltage, over-current, and load short conditions.

Feature Summary

• Integrates muting, standby, and comprehensive protection circuits including thermal, over-voltage, over-current, and load-short safeguards.
• Requires minimal external components by eliminating the need for Boucherot cells, bootstrap capacitors, and negative feedback capacitors.
• Provides high ripple rejection capability to maintain signal integrity in noisy power environments.

Applications

• TV stereo operation

Procurement Notes

Verify the specific package designation HSIP012-P-0000A against your PCB footprint requirements. Confirm that the component meets RoHS compliance standards if required by your manufacturing process. Ensure that the absolute maximum ratings, particularly supply voltage and power dissipation limits, are respected in your design to prevent device failure.

Selection Notes

Select this component for stereo audio amplification in television sets requiring a single-chip solution with integrated volume control compatibility. It is suitable for designs needing built-in mute and standby functions without additional discrete logic. Consider the thermal management requirements, as an external heatsink is necessary for optimal performance within the recommended operating temperature range.

Part Context

The AN5276 belongs to Panasonic's ICs for Audio Common Use series. It is part of a family that includes compatible models such as the AN5275 and AN5277. This series targets consumer electronics, specifically television applications, offering integrated power amplification with auxiliary control features in a compact form factor.

Replacement Considerations

The datasheet explicitly states compatibility with the AN5275 and AN5277 models. These parts may serve as functional substitutes within the same application context, provided pinout and electrical specifications align with the system design requirements.
