Set potmeters VR1 and VR2 to their middle position. Electrolytic capacitor C2 connected across 3V and ground works as a filter capacitor. The following precautions must be taken care while assembling the circuit. The voltage gain from this dual amplifier IC is not adjustable, as it is internally restricted to 39 dB only. Leave a Reply Cancel reply Your email address will not be published. From output waveforms, it was observed that on keeping the input voltage level below 45 mV, there was no clipping effect.
TDA amplifier circuit 3V to 15V operation, for handheld audio applications
It is well known for its low crossover distortion and low quiescent current. The designing of the circuit will be followed by testing of the circuit for the verification of the intended design factors. TDA amplifier circuit admin August 4, 5 Comments. VR1 and VR2 work as left- and right-channel volume controls, respectively.
The surround sound system is used in cinemas and drama theaters to give a realistic feeling to the audience. 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.
The inverting input of these amplifiers are grounded using the C9, C11 capacitor branch. The IC has the following pin diagram. Both speakers produce the same audio output after amplifying tad2822 signal from IC1.

You should hear a humming sound from left and right speakers when the screwdriver is touched at left and right inputs, respectively. Now, people like to hear the high resolution surround music just like a 3D video. The main applications of TDA are headphone amplifier, portable audio systems, mini radio, hearing aid, preamplifier etc. This IC tdda2822 operate over a tda282 range of supply voltages ranging from 3V to 15V. Embedded Hardware Engineer 28 December Internship — Image Processing Engineer 27 December The IC is designed to be used as stereo amplifier or bridge amplifier.
Thank you for your feedback. When connecting with a logarithmic potentiometer 10k entries solved the problem. Since the load impedance is now 10 ohms, the following power output from the amplifiers must be obtained. TDA is a dual power amplifier having two independent amplifier circuits on the same chip.
