Overview
The AN5277 is a monolithic dual channel SEPP power amplifier IC designed for stereo audio applications. It delivers 10.0 W output power at 26 V supply with an 8 Ω load and 10% THD. The device operates within a recommended voltage range of 10.0 to 32.0 V, with a typical value of 26 V. Absolute maximum ratings include a supply voltage of 35.0 V and power dissipation of 37.5 W at 70 °C ambient temperature. The operating ambient temperature range spans from −25 to +75 °C.
Feature Summary
- Integrates built-in muting, standby, and protection circuits including load-short, thermal, over-voltage, and current safeguards.
- Requires minimal external components by eliminating the need for Boucherot cells, bootstrap capacitors, and negative feedback capacitors.
- Provides high ripple rejection capability of 55 dB to maintain signal integrity under varying power conditions.
Applications
- TV stereo audio systems
Procurement Notes
Verify component lifecycle status before procurement as the AN5277 is classified as Maintenance/Discontinued. Consult official Panasonic semiconductor channels for current availability and replacement part recommendations. Ensure design compliance with absolute maximum ratings to prevent damage during operation or transient states.
Selection Notes
Select this component for standard TV audio applications requiring dual channel amplification without complex external filtering networks. Verify that the system can accommodate the required heatsinking for adequate thermal management. Confirm compatibility with existing control logic for mute and standby functions based on specified voltage thresholds.
Part Context
The AN5277 belongs to Panasonic's series of audio common use integrated circuits. It is functionally compatible with the AN5275 and AN5276 models, allowing for potential design continuity within similar product families. This IC represents a specialized solution for consumer electronics requiring reliable stereo power amplification.
Replacement Considerations
The datasheet explicitly lists compatibility with the AN5275 and AN5276 models. These parts may serve as functional substitutes in designs where pinout and electrical characteristics align with the original requirements.
FAQ
What are the control voltage levels for the Mute and Standby pins?
The Mute pin activates when the input voltage is 5 V and deactivates at 0 V. The Standby pin turns 'on' (active) at voltages up to 5.0 V and turns 'off' (inactive) at voltages starting from 8.5 V.
How does the thermal protection circuit behave after activation?
The temperature protection circuit operates at a junction temperature around 150 °C. If the temperature decreases, the protection circuit automatically deactivates and resumes normal operation.
