Description

The LA47536 is a 4-channel BTL power amplifier IC developed for use in car audio systems. The output stage features
a pure complimentary structure that uses V-pnp transistors on the high side and npn transistors on the low side to
provide high power and superb audio quality.

The LA47536 includes almost all the functions required for car audio use, including a standby switch, a muting function, and each protection circuit. It also provides a self-diagnosis function (output offset detection).
