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.

TDA integrated circuits series are very well apreciated and used in amplifier designs and projects. TDA audio amplifier circuits are produced in generally by Philips and SGS-THOMSON.
The most used IC is TDA2030 for small audio amplifiers kits and TDA7294 for higher power amplifiers.
In this article we present some representative amplifiers schematics with TDA circuits: car More >

Connecting two TDA2030 thru cheap power transistors we can create a amplifier wich can deliver a higher power. With the components value from the schematic the total amplifier gain is 32 dB. The speaker can be 2 ohm instead of 4 ohm if we use the TIP transistors.
