TDA2030 Bridged Audio Amplifier Circuit

This is a 35W audio power amplifier built with TDA2030 in a bridged connection with a +- 15V symmetric PS. It is easy to build, do it yourself audio amplifier which will deliver up to 35W on a 8Ω speaker. Please use a good headsink to cool down the TDA2030 power amplifier.

TDA2030 integrates circuits are very cheap and usefull if you want to start a small audio amplifier. The only thing you have to consider is to use a good power supply and heatsink or you’ll risk to burn this precious IC amplifier.

The TDA2030 is a monolithic integrated circuit in Pentawatt package, intended for use as a low frequency class AB amplifier.
Typically it provides 14W output power (d = 0.5%) at 14V/4W; at ± 14V or 28V, the guaranteed output power is 12W on a 4W load and 8W on a 8W.
