This is a 5 Watt stereo audio amplifier circuit, built based on single amplifier TA7227 chip. The TA7227 can be used for dual mode (stereo) and single mode (bridge/mono). This IC type featured some circuit protection: thermal protection, over voltage protection, current limitter and BTL DC short connection.
Rangkaian TA7227 Stereo Audio AmplifierIC TA7227 must be connected to a heat sink. A computer cabinet fan can also be used in addition. Any way better the cooling better the performance. The circuit roughly draws 5A current at 12 V at full volume.So the power supply must be any thing more than 5A. Up to 15 V can be used ,which gives a bit more power boost.Commonly used is 12 V.
