Home Engineering Projects For You. So that the audio signal from two audio channels could be obtained and the sound can be reproduced at different speakers. Now, people like to hear the high resolution surround music just like a 3D video.

Always use the filtering capacitor at the input terminal of power supply to avoid the unwanted ripples. The IC can provide a wide range of output power as per the input supply voltage and output load. The power output from the in-built operational amplifiers of the IC has been summarized in the following table.

Such a system is widely used in head phones. The IC has the following pin diagram. All Time Fav Videos! This is a filtering capacitor to remove any unwanted ripples from the power source. Use the speaker of equivalent or high power rating as amplifier output power. You may also like: Testing the circuit. Both the channels are used for applying the stereo sound to the input of the amplifier. Top 20 Computer Engineering Projects. After assembling the circuit, enclose yda2822 in a suitable box.

Fix potmeters VR1 and VR2 on the front panel of the box for left and right volume control, respectively. Always follow star topology when grounding, this will keep the noise low and reduce the problem of loop grounding. The surround sound system is used in cinemas and drama theaters to give a realistic feeling to the audience.


Always use a series capacitor at the output of the amplifier to block any DC component. Your email address will not be published. For calibration, take a tdx2822 battery; you can use two 1.

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

The IC can be used as bridge or stereo audio amplifier. Pin 2 is connected to 3V DC supply and pin 4 is connected to ground. Capacitor C12 is used for filtering the power supply. Though more number of speakers can be added to play the same audio channel but a copy of the same sound will be played on all the speakers in such system.

Hi, thanks for u r reply in main operated led. The power supply is passed through a capacitor Shown as C3 in the circuit diagram of 10 uF. The left channel input is applied to the non inverting input pin1 of the first built in amplifier stage and the right channel input is applied to the non inverting input pin 16 of the second built in amplifier.

Slowly adjust VR1 clockwise until you hear a loud humming sound from the left speaker.

Designing a Stereo Power Audio Amplifier using TDA2822H – 7/9

Both speakers produce the same audio output after amplifying the signal from IC1. Design Guides Product Development: Internship — Image Processing Engineer 27 December Previous post Next post. VR1 and VR2 work as left- and right-channel volume controls, respectively.

Awesome Timer IC Projects. The designing of the circuit will be followed by testing of the circuit for the verification of the intended design factors.


For receiving audio from the smart phone, an audio jack of 3. Always calculate the maximum power rating of the amplifier before connecting it to the speaker. Choosing Tdq2822 for Robots.

A surround sound system is designed to create a sound field like the sound is coming from back, front, left and right sides. Tdaa2822 the load impedance is now 10 ohms, the following power output from the amplifiers must be obtained. The power output specified in the above table are tested for 1 KHz frequency as per the datasheet. Interface SD Card with Arduino. For making stereo amplifier, the circuit connections are done as given in the datasheet of TDA These RC circuits help in stabilizing the output frequency.

Build Your Own Stereo Amplifier Using TDA | Full Project Available

Branches R5, C8 and R6, C10 are meant for improving the high frequency stability and preventing oscillations. The non inverting input of the second built in amplifier is grounded.

For the testing of the amplifier circuit, the function generator is used as the input source. The IC can provide a closed loop gain of ci db which is equivalent to a voltage gain of I did stereo applications. However, you can use up to uc DC. The output power of TDA amplifier can be increased by using it in mono mode using the bridge configuration and it is shown in Fig 2. Now your stereo amplifier is working and ready for use!
