80W power amplifier circuit with TDA7294

80W power amplifier circuit with TDA7294
Power Amplifier based tda7294 from ST microeletronics, you can gain power up to 100W in a single chip, for stereo unit, use similar two circuits. This circuit is based on the manufacturer's datasheet for tda7294 typical application usage. Amplifier is ready to work with a powerful signal source, if necessary, use an opamp pre-amplifier.

100W bridge amplifier based TDA7294

100W bridge amplifier based TDA7294
This 100W bridge amplifier circuit can increase the power level of the audio signal from a source that has a LINE output type. The heart of this bridge mode amplifier circuit is the TDA7294 integrated circuit which is actually a power operational amplifier with a pre-amplifier circuit, temperature control and output short circuit protection. In addition the IC is equipped with separate input Mute (Mute output) and the STBY or Stand-By (Disconnect the power amplifier). Each IC amplifies half-cycle

Monoblock Car Amplifier TDA7294

Monoblock Car Amplifier TDA7294
Monoblock Car Amplifier circuit TDA7294 is based on an article "Improving the power amplifier IC TDA7294" Journal of the radio, № 11 2005. This mono car amplifier has a sufficiently high reliability, high capacity, high-quality bass. Monoblock Car Amplifier circuit is shown above. The difference from the original circuit only in the output transistor using a better replacement. (more…)
