Overview

The LA47510 is a BTL 4-channel (50W×4) power IC for carstereo. The output stage uses a pure complementary format with a V-PNP transistor on the upper side and a NPN transistor on the lower side, making it possible to obtain high power output and excellent sound quality. This IC incorporates various functions (standby switch, mute function, full complement of protection circuits) needed for car audio, and also has a self-check (output offset detection) function.

Functions & Features
