This amplifier design really excels in simplicity and robustness, thanks to the
use of the TDA2030 or TDA2040 “power op amps”, The power supply of the amplifier is built with bridge rectifier and elcap capacitor. Further stabilization is not necessary because of the high supply voltage ripple rejection (50dB).
Here are some features :
- Short circuit proof outputs.
- Built in thermal protection.
- High supply voltage ripple rejection: no supply stabilization necessary
