For calibration, take a 3V battery; you can use two 1. However, you can use up to 6V DC. The right speaker LS2 is connected to output pin 3 through if capacitor C4.

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

The surround sound system is used in cinemas and drama theaters to give a realistic feeling to the audience. Basics, Usage, Parameters and Applications. You may also like: Please enter your name here. The following precautions must be taken care while assembling the circuit.

Build Your Own Stereo Amplifier Using TDA2822

This has brought a revolution in the music industry. Pins 5 and 8 are tied together and connected to ground via electrolytic capacitor C1. Millions of engineers and scientists worldwide use MATLAB to analyze and design the systems and products transforming TDA is a dual power amplifier having two independent amplifier circuits on the same chip.

An alternative to the surround sound system is stereo audio system. Ix designing a stereo sound system there are two ta2822 required as well ix the audio source is required which can provide the stereo sound. After assembling the circuit, enclose it in a suitable box. TDA amplifier circuit admin August 4, 5 Comments.

The IC is designed to be used as stereo amplifier or bridge amplifier. Power Bank for Smartphones. The IC can provide a closed loop gain of 39 db which is equivalent to a oc gain of 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.


The function generator is used to generate a sine wave of constant amplitude and frequency. Any DC component from the amplifier to the load which is the speaker in this case can damage it or produce noise or distortion in the output audio. As the speakers used at the output have 8 ohms impedance and supply voltage of 9 V is provided to the IC, the typical power output of the OPAM should be 1 Watt. The root mean square RMS voltage at the output can be calculated by the following equation.

Log in or register to post comments reads.

For testing of the amplifier circuit, first the input voltage is set between the applicable range up to 45 mV. The circuit diagram is straightforward.

How the circuit works. A resource tda8222 professional design engineers. In place of speaker, a dummy load which is purely resistive is used.

The main applications of TDA are headphone amplifier, portable audio systems, mini radio, hearing aid, preamplifier etc. Always use a series capacitor at the output of the amplifier to block any DC component.

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

Internship — Image Processing Engineer 27 December gda2822 Both speakers produce the same audio output after tdaa2822 the signal from IC1. The amplifier will be designed to supply audio to two speakers having an impedance of 8 ohms. This high-density System-in-Package SiP integrates controller, power switches, and support components. As the amplifier is designed for both channels, both of the channel wires will be connected to the amplifier as audio input. The audio signal is a sine wave so its peak to peak voltage for 1 Watt power can be calculated as follow.


The IC has the following pin diagram.

Career advice and jobs related to electronics and IOT. Virgin Galactic — Commercial Space Flight. The power output specified in the above table are tested for 1 KHz frequency as per the datasheet.

For a stereo sound system, the same number of amplifiers are required as the number of audio channels. Interface SD Card with Arduino.

tds2822 Useful Raspberry Pi Projects. Since the load impedance is now 10 ohms, the following power output from the amplifiers must be obtained. The amplified outputs left and right are available at pins 6 and 11 of the IC.

TDA audio amplifier circuit. Both the channels are used for applying the stereo sound to the input of the amplifier. Thank you for your feedback. For the testing of the amplifier circuit, the function generator is used as the input source. Fix potmeters VR1 and VR2 on the front panel of the box for left and right volume control, respectively.

Exclusive Digi-key Tools Embedded computers. The voltage gain is internally set to be 39 dB or 90 which cannot be changed. Set potmeters VR1 and VR2 to their middle position. So, practically the power output of this stereo amplifier for actual load that are the speakers vary between mW to 1 watt.

The 10 Watt speakers instead of 6 Watt are used as per the availability.
