Have you ever read an amplifier review and encountered the terms Class A, Class A/B or Class D? We explain all.

Historically, amplifier class designations were related to the biasing of amplifier devices—that is, over how many degrees of each input-signal swing they conducted.

Class A amplifiers can be made very linear, but their efficiency is limited. In theory, a class A amp can achieve 50% efficiency with inductive output coupling or 25% with capacitive coupling.
