LM4702 Power Amplifier Circuit Schematic


This application note will present several useful design techniques  and practices that will assist the reader in creating a successful audio power amplifier design utilizing the LM4702. Following these steps will result in an amplifier that measures well in the universally accepted key parameters such as THD+N (0.0006% THD), SNR, Frequency Response, Noise and other audio specifications. In addition, these techniques will also assist the designer in creating an audio amplifier that has performance comparable to other amplifiers which are considered high fidelity.

The topics discussed inside the application note including the introduction, application information, power supply design and transformer shielding techniques, sound quality, power supply bias capacitor, wiring techniques, bill of materials, and many more.
