National LM386 Audio Power Amplifier Datasheet for Battery Operation

This device has 24 milliwatts quiescent power drain when operating from 6 V supply in which making the LM386 ideal for battery operation. It is stated in the application hints section ofLM386 datasheet, there are two pins (1 and 8 ) provided for gain control in order to make this device more versatile amplifier. You can put a capacitor from pin 1 to 8 bypassing the

1. 35 kOhms resistor, placing a resistor in series with the capacitor, or capacitively coupling a resistor (or FET) from pin 1 to ground to set the gain. You will also see typical applications forLM386 in circuit schematici. e Amplifier with Gain (20, 50, 200), Low Distortion Power Wienbridge Oscillator (click to enlarge), Amplifier with Bass Boost, Square Wave Oscillator, and AM Radio Power Amplifier.
