Introduction
Tda7297 is a dual bridge audio amplifier IC, and it can provide the output wattage of 15 watts per dual channel ( 15 watts + 15 watts). The amplifier IC is designed as bridge mode so the speaker impedance should be around 8 ohms. The efficiency and low distortion is amazing as compared with any other audio amplifier circuits.
The wide range of supply voltage we can provide is around 6.5 v to 20V dc supply, so this is very helpful for making car audio amplifier circuits. There are several additional features available like, stand by and mute function along with short circuit protection and overload protection.

Another advantage of this audio amplifier circuit is the minimal number of components used in the circuit. The minimal components usage is quite easiest to build on a breadboard or as a DIY project.
