2.5W Stereo Audio Amplifier using LM4752

The Stereo Audio Amplifier project shown here is capable of delivering 2.5W per channel of continuous average output power to 4Ω loads using a single 12V supply at 10% THD+N. The project is built using the LM4752 chip. This chip is specifically designed for single supply operations and low external components count. The gain and bias resistors are integrated on-chip, resulting in a 2.5W stereo amplifier in a compact 7-pin TO263 SMD package. High output power levels at 12V supplies and low external component count offer high value for compact stereo and TV applications. Sufficient power dissipation is provided on PCB so no external heatsink is required for IC.
