The LM386 power amplifier is designed for use in low voltage consumer applications such as AM-FM radio amplifiers, power converters, small servo drivers, ultrasonic drivers, line drivers, TV sound ...
What is the LM386 audio amplifier? The integrated chip LM386 is a low power audio frequency amplifier requiring a low level power supply (most often batteries). It comes in an 8-pin mini-DIP package.
Hello everyone! I simulate a LM386 circuit in LTSpice and I'm getting almost the right output dc offset voltage (+5V), but the frequency response I get as result can't be right. The amplifier amplifies up to 0dB... I run a transient response analysis with Vin (dc offset=0V, Amplitude=50mV...
I want to reduce the gain of the lm386 further below 20 such that it does not distort my single coil pickups When I add a resistor across pins 1 and 8, it simply increases the gain.
The lm386 is a good amplifer, however I want to reproduce the amplifier circuit using transistors, preferbly less that 2 transistors. Can't even be done with 2. You need at least one gain stage and a low impedance output stage.
The LM386 should be plenty loud enough from a 12v DC supply. If you used the low gain circuit shown in your first link it should work fine, but I think you should try to capacitor couple the input wire (input signal goes through a 47uF electro cap). Otherwise you might have a grounding issue, is the 12v supply for the LM386 used for anything else? If it is a little 12v plugpack just used for ...
