Headphone/Audio Amplifier Circuit on PCB using LM386
https://circuitdigest.com/electronic-circuits/headphone-amplifier-circuit-on-pcb/
This Headphone Amplifier Circuit is made by using LM386 Audio Amplifier IC. This circuit is made in such a way that user can not only use it as Headphone Amplifier but also can drive a subwoofer speaker or normal speaker (4 ohms) and can get a amazingly loud sound through the speaker. To switch it between these two modes we have used three jumpers here.

This HiFi headphone amplifier circuit design is normally used to drive a headphone with a relative low impedance. It provides one watt power output and it can also be applied as an output stage for preamplifiers in conjuction with active loudspeakers boxes. The headphone amp is composed of an OP-AMP and an additional transistor amplifier.

Intergraded circuits U1 and U2 are LM386 amplifiers. LM386 can provide up to 325mW into an 8Ω load. Standard headphones usually have greater impedance than this, so the available output will be reduced. However, this does not matter because only a very small output is sufficient to fully load the headphones.

The variable clipper in figure 6b puts the audio signal through an inverting amplifier, the output of which connects to the bottom of the zener array. The limiter clips when the audio signal exceeds |(V f + V z) / (1 + (R2 * R5 / R3 * Rx))|, where V f is the forward bias voltage of a zener and V z is the breakdown voltage. R5 adjusts the feedback of the inverting …
