The TDA 2003 hasimproved performancewith the
same pin configuration as the TDA 2002. The additional features of TDA 2002, very low numberof externalcomponents,ease of assembly, space and cost saving, are maintained. Thedeviceprovidesa high outputcurrentcapability (up to 3.5A) very low harmonic and cross-over distortion. Completely safe operation is guaranteed due to protectionagainst DCand ACshort circuit between all pins and ground,thermal over-range,load dump voltage surge up to 40V and fortuitous open ground.
The main means of doing this are magnifying these:
- Resistor 20k
- Capacitor 1000 uf,25v
- Capacitor 2.2uf,50v
Copper plate then we do the voice connection magnifier.
Then place the electronic components and begin to capture them in certain places and tin soldering . I noticed that created one of 10w amp
