After successfully building my LM3886-based gainclone project amplifier, I’ve decided to build a version better suited to driving low-impedance loads. This leads me to the LM4780 chip from TI, which is just two LM3886 dies in one package. It can be used as a stereo amp, or a bridged or paralleled mono amplifier. The datasheet […]
