The circuit diagram shows 10k and 3-15v. The voltage might be on the low side. A bench power supply would be useful for testing?
TDA2822 Audio Amplifier Circuit Problem
Good day, all
I would like to ask about an amplifier circuit I assembled today.
I used the TDA2822 and connected it to two 1 inch 8 ohm speakers, and a 3.6v lithium battery and connected it to my PC/Mobile.
But the sound is very loud and noisy when I turn down the stereo potentiometer (It works fine only on the highest resistance value) , so is it the 10k potentiometer (should I use 100K?) or is it lack of voltage? and if so should I use another amp, circuit that works better with 3.6v battery and what do suggest? or is it something else like capacitors (I used 1000uF instead of 470)
Any suggestion will be appreciate!
