Perform thermal tests on Class D amps
Author:Robert Polleros

There are two kinds of amplifiers used to generate the output power, class AB and class D amplifiers. The shift to class D was mainly the result of the introduction of flat-screen LCD and plasma TVs, in which space was limited and heat dissipation became an issue. Since the thermal test standards were developed when only class output power AB was used, we want to investigate if they are still appropriate for class D.
