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. - Using Thermal Calculation Tools for Analog ComponentsPDF, 1.1 Mb, File published: Sep 2, 2010
This document provides general guidance on the use of toolsand calculations for thermal estimates of component operating temperatures for analog devices. Of particularfocus are components with direct thermal paths to the PCB which is common for components which need a low thermal resistance to manage the dissipated power.
