Bridge amplifier circuit – Tda7294 is a monolithic integrated circuit with multi watts. and the high power output is about 100w. most commonly used in this IC in-home stereo self-powered loudspeaker and TV. and thanks to the wide range of voltage and high output current capability it is able to supply the highest power into both 4 ohms and 8 ohms loudspeaker.
TDA7294 Bridge Amplifier Circuit
The recommended transformer is 12 0 12, 25 0 25 5 ampere. the power supply is a simple symmetrical type with a bridge rectifier and capacitor being too large electrolytic from 4700 microfarads to 12000 microfarads with 50 volts.

- The main advantage of earthing is the high power performance with a WIDE RANGE power supply level.
- Considerable e the output power even with high load values at 16 ohms.
- With the voltage is 25 volt the maximum power output is obtainable is about 150 watts. Pretty good.
- In the bridge mode, the manufacturer does not recommend using the speaker with an impedance of fewer than 8 ohms.
