Exclusive Digi-key Tools Embedded computers. This IC has been especially designed for use in portable radios and transistor sets. Always use a series capacitor at the output of the amplifier to block any DC component. Choosing Motor For Robots. The voltage gain is internally set to be tda222 dB or 90 which cannot be changed.

Designing a Stereo Power Audio Amplifier using TDAH 7/9 | EngineersGarage

The IC can be used as bridge or stereo audio amplifier. Avoid clipping of the output signal as it may damage the speaker. Testing the circuit.

Log in or register to post comments lc. Career advice and jobs related to electronics and IOT. In the circuit designed in this tutorial, the IC is used as stereo power amplifier to boost to audio channels and output audio to two separate speakers. Useful Raspberry Pi Projects.

Build Your Own Stereo Amplifier Using TDA | Full Project Available

Such a system is widely used in head phones. The amplified outputs left and right are available at pins 6 and 11 of the IC. You may also like: For designing a stereo sound system there are two channels required as well as the audio source is required which can provide the stereo sound.


The TDA is used as a stereo power amplifier in the circuit. 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. TDA audio amplifier circuit. For making stereo amplifier, the circuit connections are done as given in the datasheet of TDA Take a metal screwdriver and gently touch on input pin 6 or 7 of IC1.

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. Awesome Timer IC Projects.

Always follow star topology when grounding, this will keep the noise low and reduce the problem of loop grounding. Thank you for your feedback. Slowly adjust VR1 clockwise until you hear a loud humming sound from the left speaker.

The IC is designed to be used as stereo amplifier or bridge amplifier. As the amplifier is designed for both channels, both of the channel wires will be connected to the amplifier as audio input. Arduino based GPS receiver. So, practically the power output of this stereo oc for actual load that are the speakers vary between mW to 1 watt.

Build Your Own Stereo Amplifier Using TDA2822

The speakers are connected at pins 1 and 3 of the IC which are the output pins of the TDA and the ground wires tda28222 the speakers are connected to the common ground. The audio signal is a sine wave so its peak to peak voltage for 1 Watt power can be calculated as follow.


If circuit diagram is straightforward. The circuit works off 3V DC. So, the maximum amplitude voltage level in the input audio signals should not be greater than 45 mV otherwise, the output signal will start clipping. Log into your account. The following precautions must be taken care while assembling the circuit. This high-density System-in-Package SiP integrates controller, power switches, and support components.

Always calculate the maximum power rating of the amplifier before connecting it to the speaker.

The frequency of the input signal is set to 1 KHz. An alternative to the surround sound system is stereo audio system. The stereo power amplifier designed in this tutorial can be used tdaa2822 portable cassette players. This has brought a revolution in the music industry. A surround sound system is designed to create a sound field like the sound is coming from back, front, left and right sides. Millions of engineers and scientists worldwide use MATLAB to analyze and design the systems and products transforming Both the channels are used for applying tfa2822 stereo sound to the input of the amplifier.

Any audio signal is also basically tdaa2822 sine wave so a function generator can be used instead of using a microphone or actual audio source. TDA amplifier circuit admin August 4, 5 Comments.
