Hello , This Video is about checking the stability of the LM3886 Board. For Stability I will be checking the Square wave response of the amplifier and then will make it force Oscillate to see if it dampens out the oscillation or not . I will be using two capacitors of values 10nF and 0.15uF to create a situation of oscillation. I will also show how the THIELE NETWORK reduces the oscillation as it can reduce the effect of capacitance in the output. Then we will test if the Amplifier is giving flat response or not throughout the Audio Frequency Range. I don't have Frequency Sweep option in my Signal Gen but I will try to keep the Input Amplitude same for all the frequencies that I will test the Amplifier with . So for different Frequencies and same input Amplitude we will note if the output amplitude varies or not .1dB to 2dB change in the output amplitude is expected and accepted in Audiophile level .
The Results will be excellent as the LM3886 chip amp is very well designed.
