WEEK 9

Comparison Study of audio amplifier performances using Class AB, B and D topologies in portable audio devices.


For week 9, I doing discussion with my supervisor for design n construct the circuit of Class AB Audio amplifier using TDA 2030. After successful design and construct this circuit, I'm test the circuit in lab to getting the result displays at Oscilloscope.

The pictures below is the circuit of Class AB Audio amplifier  using TDA 2030 that I'm successful design and construct:


Figure 13: The complete circuit of Class AB using TDA 2030


Figure 14: Testing circuit with Function generator and Oscilloscope


Figure 15: The result displays at Oscilloscope

For this circuit, the noise very high and so that we cannot hear the audio properly.
