In this week, I design, test and construct the circuit of Class AB audio amplifier using TDA 2003 after buying all the component. The TDA 2003 provides a high output current capability, very low harmonic and cross over distortion.
TDA 2003 characteristics:
- Operating power supply (Min 8, Max 18V)
- Power dissipation at Tcase = 20W
- Storage and junction temperature = -40 to 150 C
- Frequency response = 40 - 15000 Hz
The pictures below is the circuit of Class AB audio amplifier using TDA 2003 that I'm successful design and construct:
