This audio amplifier circuit delivers up to 200 W of top-class quality for loudspeaker from 4 to 16 ohm. Operating voltage is between 24 and 36 V, max 5 A. The frequency response is from 20 to 20000 Hz.
Please take special care that the transistors and the IC’s have been fixed firmly and solely one or two separated cooling elements with sufficient dimensions for this purpose (thermal resistance < 1K/W).
This is a 35W audio power amplifier built with TDA2030 in a bridge 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.
A great 40 W audio mono amplifier built with TDA 2030, BD 712 and BD 711. The output power is 22W on 8 ohm speaker and 40W on 4 ohm. Distorsions are 0.012% at 1khz/8 ohm/11W and 0.032% at 1khz/4 ohm/20W.
TDA2030 datasheet – 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.
