Application Notes
- AN-1737 Managing EMI in Class D Audio Applications (Rev. A)PDF, 140 Kb, Revision: A, File published: May 1, 2013
Electromagnetic interference (EMI) is an unwanted disturbance caused in an electrical circuit byelectromagnetic radiation emitted from an external source. The disturbance may interrupt, obstruct, orotherwise degrade the effective performance of the circuit. - AN-1849 An Audio Amplifier Power Supply Design (Rev. B)PDF, 1.9 Mb, Revision: B, File published: May 1, 2013
