Bridge Power Amplifier Using TDA7294

Using TDA7294 audio amplifier integrated circuit in bridge mode configuration , can be designed another Hi-Fi power amplifier .In this TDA7294 bridge power amplifier the value of the load must not be lower than 8 Ohm for dissipation and current capability reasons.

Bridge Power Amplifier Circuit Using TDA7294

The main advantages offered by TDA7294 bridge mode configuration are:High power performances with limited supply voltage level, Considerably high output power even with high load values ( 16 Ohm).The output power of this amplifier in bridge connection is 150 W with Rl= 8 Ohm , Vs = +/-25V the and 170 W output power for Rl=16 Ohm, Vs = +/-35V.
