Electrolytic capacitor C2 connected across 3V and ground works as a filter capacitor. Any audio signal is also basically a sine wave so a function generator can be used instead of using a microphone or actual audio source. The power output specified in the above table are tested for 1 KHz frequency as per the datasheet.

TDA amplifier circuit 3V to 15V operation, for handheld audio applications

Always follow star topology when grounding, this will keep the noise low and reduce the problem of loop grounding. Branches R5, C8 and R6, C10 are meant for improving the high frequency stability and preventing oscillations. Set potmeters VR1 and VR2 to their middle position.

Then, the output waveform is observed at CRO and the input signal is increased until the output waveform starts clipping. Embedded Hardware Engineer 28 December The IC can be used as bridge or stereo audio amplifier.


This IC can operate over a wide range of supply voltages ranging from 3V to 15V. In place of speaker, a dummy load which is purely resistive is used.

This is a filtering capacitor to remove any unwanted ripples from the power source. For a stereo sound system, the same number of amplifiers are required as the number of audio channels.

Build Your Own Stereo Amplifier Using TDA2822

You may also like: A resource for professional design engineers. TDA is a dual power amplifier having two independent amplifier circuits on the same chip.

Pins 5 and 8 are tied together and connected to ground via electrolytic capacitor C1. You should hear a humming sound from left and right speakers when the screwdriver is tda28222 at left and right inputs, respectively.

Always calculate the maximum power rating of the amplifier before connecting it to the speaker. C7 is the power supply filter capacitor.

Fix potmeters VR1 and VR2 on the front panel of the box tdx2822 left and right volume control, respectively. Such a system is widely used in head phones. The root mean square RMS voltage at the output can be calculated by the following equation.


Power Bank for Smartphones.

Always place the components as close as possible to reduce the noise in the circuit. So, practically the power output of this stereo amplifier for actual load that are the speakers vary between mW to 1 watt.

The frequency of the input signal is set to 1 KHz. Over the last decade, there is growth in the audiophile.
