1W Stereo Headphone Amplifier using TDA2822 IC + PCB

PCB – 1W Amplifier for Stereo Headphone with IC TDA2822M

Simple headphone amplifier with few external components that is easy and inexpensive to assemble. This IC is designed for amplifying portable devices such as CD players, portable radios, small speakers, etc.

First of all, we will use it to amplify audio signal for headphones, that is, we will build a headphone amplifier, whether to listen to music from a mobile phone, connect instruments to study, such as electric guitar, bass guitar, ukulele, guitar, or any other audio signal that needs to be amplified.

The main component is the TDA2822, a monolithic integrated circuit in an 8-pin lead Mini-dip package. It is intended for use as a dual audio power amplifier in portable audios.

FEATURES

Dual Low-voltage power amplifier
Supply voltage down to 1.8V
Low crossover distortion
Low quiescent current z Bridge or stereo configuration

The maximum input voltage of this IC is 15V DC, so do not apply more than 15V to IC. The circuit volume can be adjusted using a 47K doble potentiometer is used in circuit.

The schematic diagram circuit of 1W audio Amplifier for Stereo Headphone with IC TDA2822M is shown in Figure 2 below.
