WEEK 10

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

For this week, I'm doing some discussion with my supervisor to design and construct the another circuit of Class AB audio amplifier using TDA 2003. Objective doing the another circuit is want to make comparison between using TDA 2003 and TDA 2030. 

Other that, I'm doing some research about this TDA 2003 and go buying all the components. Picture below is the circuit diagram that I'm being used:

Figure 14:Circuit diagram TDA 2003

Figure 15: Connection diagram 

Component:

1. IC = TDA 2003
2. Resistor = 15K, 3.3R, 220R and 1R
3. Capacitor = 10uF, 100uF, 100uF, 1000uF, 0.1 and 0.1
4. Speaker = 8 ohm
5. Heat sink
6. Variable resistance
