LM386N AUDIO AMPLIFIER 8 PIN
Description:
- The LM386N offers a straightforward solution for low-voltage audio amplification.
- It requires few external components to function, simplifying the design process and lowering overall component costs.
- The amplifier's gain can be readily modified by adding external resistors and capacitors, providing greater versatility in audio applications.
- Wide supply voltage range: Basic models operate between 4V and 12V, with some versions supporting up to 18V.
- adjusted Gain: The default voltage gains of 20 is adjusted up to 200 with external components, providing for more flexible amplification requirements.
- Low Quiescent Current: Consumes only 4mA, making it perfect for battery-operated applications.
- Low Distortion: Achieves high-quality audio output with a total harmonic distortion of only 0.2% at 6V and 125mW.
- Minimal External Components: Simplifies circuit design by requiring only a few external components.
- Self-Centred Output Quiescent Voltage: The output is automatically biased to one-half the source voltage, ensuring simple operation.
- Ground-Referenced Input: Stabilizes the input signal reference, which improves performance.
