National LM386 Audio Power Amplifier Datasheet for Battery Operation


Posted on Feb 5, 2014

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
