Build a 22 watt stereo car audio amplifier with TD1557Q IC. The circuit need a few external component and 12 volt DC power supply to work. Car audio system we need to consider the low cost IC and high-performance. This TD1557Q IC can deliver up to 22 W at 4 OHMS load. This IC is designed with BTL configuration to maximize the output power. And it usually available in single line package, which is suitable for easy mounting on PCB. When using this Audio IC we need to care about the heat control. You can add proper Heat Sink to solve the overheating issue.
