Audio Amplifiers and Preamplifiers Datasheets

Audio amplifiers and audio preamplifiers are used to increase the amplitude of sound signals.  Preamplifiers or preamps are designed to amplify low-level signal from a high-impedance device such as a microphone or instrument pick-up. After pre-amplification, the signal is sent to a power amplifier or amp, which provides the higher current necessary to drive the speakers.
