Lm386 Audio Amplifier Arduino. This is how i was introduced to the bodacious lm386. Hence we amplify it by using the lm386 low voltage audio amplifier ic.
Circuit designed for 200 gain. But the audio signals are not so clear hence we have amplified it by using the lm386 audio amplifier module. Hence we amplify it by using the lm386 low voltage audio amplifier ic.
The amplifier shown above is designed for a gain of 200 and the vdd pin 6 is powered by the 5v pin of the arduino.
Which means its performance is based on the assumption that it will be driving speakers. Which means its performance is based on the assumption that it will be driving speakers. Nowadays we all use class d amplifiers most of the time because it is more efficient small size and most importantly the audio quality is also great. The lm386 is an operational amplifier than has been specifically designed for use in audio applications.
