General output stage of power amplifier has a difficult and complex problem about heat sink designing and its setting. Sanyo’s D.P.P. intends to decrease eletronic parts and rationalize a manufacturing process by designing IC of only output stage of power amplifier.

An AF (Audio Frequency) Power Amplifier is an electronic device or circuit designed to amplify low-frequency audio signals, typically in the range of human hearing (20 Hz to 20,000 Hz). The primary purpose of an AF power amplifier is to take a weak audio signal, such as the output from a microphone, a musical instrument, or an audio source, and increase its power and voltage level to drive a loudspeaker or headphones, thereby producing audible sound.
