Calculating Gain for Audio Amplifiers (TI)

ABSTRACT
  This application report explains the different types of audio power
amplifier configurations, such as the single-ended (SE), the bridge-tied
load (BTL) and the fully differential audio amplifier. Each configuration is
illustrated with a block diagram, gain equations, and an example using
realistic scenarios to illustrate to engineers how to calculate the gain of
their audio amplifier.
