5pcs Audio Amplifier Integrated Circuit

An Audio Amplifier Integrated Circuit is a type of electronic amplifier that is used to boost the magnitude of a given input signal. The input signal’s strength is boosted to a level sufficient to drive loads of output devices such as speakers, headphones, RF transmitters, and so on. A power amplifier, as compared to a voltage/current amplifier, is meant to drive loads directly and is used as the final block in an amplifier chain.

An Audio Amplifier Integrated Circuit’s input signal must be greater than a specified threshold. So, rather than sending the raw audio/RF signal directly to the power amplifier, it is first pre-amplified using current/voltage amplifiers before being sent as input to the power amplifier after appropriate modifications.
