Active PC Loudspeaker

With the well-known TDA2030V integrated power amplifier in the Pentawatt package, it is easy to ‘activate’ a PC loudspeaker or upgrade the quality of an inexpensive active loudspeaker. The TDA2030 combines ease of use with low levels of harmonic and crossover distortion, and it is also incorporates short circuit and thermal overload protection.No creative brilliance is needed to arrive at the circuit shown in Figure 1, which is practically the same as the standard application circuit for single-supply operation as shown in the device data sheet from its manufacturer.
