Additional Information:
Key Features:
- BTL-OCL configuration: Provides high power output without the need for output capacitors.
- Built-in functions:
- Starting time pop noise suppressor: Reduces unwanted noise during startup.
- On-chip audio muting: Allows for muting the audio signal.
- On-chip thermal detector/protector: Protects the IC from overheating (Tj=170 to 180°c).
- On-chip overvoltage/surge protector: Protects the IC from voltage surges (Vccsurge=24V).
- On-chip output pin-to-GND short protector: Protects against short circuits between the output and ground.
- On-chip output pin-to-Vcc short protector: Protects against short circuits between the output and the power supply.
- On-chip load short protector.
- Small-sized package: SEP-14HS (Zigzag pins).
Use Cases and Benefits:
- Car Stereos: Designed specifically for car audio applications.
- High Power Output: Delivers 20W of power for a single channel.
- Protection Features: Comprehensive protection circuits ensure the IC's reliability and longevity.
- Reduced External Components: Integrated features minimize the need for external components, simplifying circuit design.
Additional Information:
- The LA4476 has an inverted pin layout compared to the LA4470 and LA4475.
- It is suitable for applications requiring robust audio amplification with built-in protection mechanisms.
