Product Description: LM4871 SOP 3W Audio Power Amplifier with Shutdown Mode
The LM4871 is a high-performance, mono bridged audio power amplifier capable of delivering 3W of continuous average power into a 3Ω load with less than 10% THD when powered by a 5V supply. It is designed for low-power portable systems, requiring minimal external components and operating on low supply voltages from 2.0V to 5.5V. The amplifier features a micropower shutdown mode with a typical current of 0.6µA, making it ideal for battery-powered devices.
Features:
- Output Power: 3W into a 3Ω load (typical), 1.5W into an 8Ω load (typical).
- THD+N at 1kHz: Less than 10% at 3W into 3Ω, 0.5% at 1W into 8Ω.
- Supply Voltage Range: 2.0V to 5.5V.
- Shutdown Current: 0.6µA (typical).
- No Output Coupling Capacitors Required: Simplifies circuit design.
- Unity-Gain Stable: Allows for external gain configuration.
- Packaging Options: SOP-8, MSOP, SO, or DIP.
- Thermal Shutdown Protection: Prevents overheating.
- External Gain Configuration Capability: Allows customization of gain settings.
Application:
This amplifier is commonly used in portable computers, desktop computers, and low-voltage audio systems. It is suitable for applications requiring high power, high fidelity audio output with minimal volume and weight.
