Product Overview
LV47011P: Audio Power Amplifier, Class AB, 4-Channel, 50 W
For complete documentation, see the data sheet
Product Description
The LV47011P is the IC for 4-channel BTL power amplifier that is developed for car audio system. Pch DMOS in the upper side of
the output stage and Nch DMOS in the lower side of the output stage are complimentary. High power and high quality sound are
realized by that. This IC incorporate various functions (standby switch, muting function, and various protection circuit) necessary for
car audio system. Also, it has a self-diagnosis function.
