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.
Headphone Amplifier for Voltage-Output Audio DACs
https://www.ti.com/lit/ug/tiduaw1/tiduaw1.pdf
This headphone amplifier circuit converts the output signal from an audio digital-to-analog converter (DAC) into a single-ended signal suitable for headphones. An op amp is configured as a difference amplifier to convert the differential output voltage from a DAC to single-ended. The circuit is designed to operate from

The headphone amplifier delivers an output of around 1 watt. Use a power supply rated at 350 mA. The amplifier gain is dependent of the resistors R4 and R6. The values shown in the circuit gives a gain of 11. The voltage at the junction of R13 and R14 must be set at 50% of the power supply. This can be set through P2.

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.
