The LM386 is a low voltage audio power amplifier integrated circuit (IC) widely used in various audio applications. It’s compact, efficient, and requires minimal external components, making it an excellent choice for hobbyists and professional engineers alike.
Pin Configuration:
- Pin 1 & 8: Gain Control – Adding a capacitor between these pins increases the gain.
- Pin 2: Inverting Input (-).
- Pin 3: Non-inverting Input (+).
- Pin 4: Ground (GND).
- Pin 5: Output.
- Pin 6: Supply Voltage (Vcc).
- Pin 7: Bypass – Used to connect a capacitor for noise filtering.
Features of LM386:
- Wide Operating Voltage Range: It operates on a voltage range of 4V to 12V (or 5V to 18V for some variants).
- Low Power Consumption: Ideal for battery-operated devices.
- Adjustable Gain: The gain is internally set to 20, but it can be increased up to 200 using an external capacitor and resistor.
- Low Distortion: Ensures high-quality sound output.
- Minimal External Components: Requires only a few passive components to function.
- Built-in Thermal Shutdown: Protects the IC from overheating.
- Small Package Size: Available in an 8-pin DIP or SOIC package.
Basic Circuit Design: A simple LM386 amplifier circuit includes:
- Input coupling capacitor: Blocks DC from the input source.
- Bypass capacitor: Reduces noise and stabilizes operation.
- Gain capacitor: Optional; increases gain.
- Output coupling capacitor: Blocks DC from the speaker.
- Decoupling capacitor: Stabilizes the power supply.
Technical Specifications:
- Output Power: Up to 1W (depending on supply voltage and load impedance).
- Input Impedance: Typically 50kΩ.
- Frequency Response: Wide bandwidth from 20Hz to 300kHz.
- Total Harmonic Distortion (THD): Less than 0.2%
Applications:
- Battery-powered audio devices
- Speaker drivers
- Intercom systems
- Portable audio amplifiers
- Radio and TV sound systems
Package Includes:
- 1 Piece- LM386 Low Voltage Audio Power Amplifier IC
