Audio Amplifier IC LM386L

The Audio Amplifier IC LM386L is a low-voltage audio power amplifier with 8 pins, the lead-free version of the classic LM386. It runs from 4 V to 12 V, needs only a few external parts and can drive a small 8 Ω speaker directly, which makes it the usual choice for mini speakers, intercoms, radios and Arduino sound projects.

Audio Amplifier IC LM386L Specifications

• Type: low-voltage audio power amplifier (LM386, lead-free L version)
• Supply voltage: 4 V to 12 V
• Voltage gain: 20 (26 dB) with pins 1 and 8 open, up to 200 (46 dB) with 10 µF between pins 1 and 8
• Output power: up to about 0.7 W into 8 Ω at 9 V (10% THD)
• Quiescent current: about 4 mA at 6 V
• Pinout: 1 and 8 gain, 2 −input, 3 +input, 4 GND, 5 output, 6 VCC, 7 bypass

Audio Amplifier IC LM386L Applications

• Small speaker amplifiers and portable radios
• Intercoms and baby monitors
• Sound output for Arduino, ESP32 and 555 tone circuits
• Guitar mini amps and practice amplifiers
• Audio signal tracers for testing circuits

What's in the Box

• 1 × LM386L audio amplifier IC

Tip: Connect the speaker to pin 5 through a 220–250 µF capacitor, add 0.05 µF in series with 10 Ω from pin 5 to GND to keep it stable, and decouple VCC with about 100 µF close to the chip. The LM386 has a lot of gain, so turn a microcontroller signal down with a potentiometer before feeding it in.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
