AN7511

Overview

The AN7511 is a single-channel audio power amplifier IC manufactured by Panasonic Electronic Components. It utilizes a BTL (Balanced Transformer-Less) output configuration to deliver up to 1 W of power into an 8 Ω load with a 5 V supply. The device operates within a supply voltage range of 3.5 V to 13.5 V and features integrated standby and muting functions for power management. It includes thermal shutdown protection and ripple rejection circuits, housed in an 8-pin DIP package.

Feature Summary

• Single-channel BTL output architecture
• Integrated standby and muting control
• Thermal shutdown protection circuit

Applications

• Televisions
• Radios
• Personal computers

Procurement Notes

Verify the current lifecycle status before procurement as the component may be discontinued or under maintenance plans. Confirm that the required operating temperature range aligns with the specified -25°C to +70°C limit. Ensure design compliance with absolute maximum ratings, particularly regarding supply voltage and power dissipation limits at elevated ambient temperatures.

Selection Notes

Select this component for applications requiring a simple, low-part-count mono audio amplifier solution. The BTL topology reduces external component requirements compared to traditional configurations. Consider the integrated standby and mute pins for system-level power control and noise reduction during startup or shutdown sequences.

Part Context

This part belongs to the category of ICs for Audio Common Use. It serves as a dedicated audio power amplifier designed for general electronic equipment such as household appliances and office equipment. The product is distinct from automotive or high-reliability specialized amplifiers.

Replacement Considerations
