Module pratique, pas cher, basé sur un schéma simple. Les LM1875T doivent être isolés du refroidisseur car portés à la tension d'alimentation négative.
Puissance suffisante pour la majorité des usages.

Amplifier module 2x LM1875 Stereo 2x20W Class AB
This MA-LM01 stereo amplifier module is powered by two LM1875 TI amplifier chips. Thus, this amplifier is capable of delivering 2x20W at 8 Ohm with a distortion of only 0.015% (@ 1kHz). The module benefits from a beautiful design with a double-sided PCB and gold-plated circuits that greatly improve conductivity. At the output the amplifier integrates two OFC Copper inductors to reduce interference for a cleaner reproduction. Finally, we note the presence of a protection circuit based on an Omron G2R relay.
This module needs to be associated with a heat sink.
