ICs for Audio Common Use AN7551Z Power IC for BTL car audio s Overview The AN7551Z is an audio power IC developed as a car audio output (35 W × 4-ch).

CR to stop oscillation is built in between the output pin and GND so that a space saving of set is possible.

Also, it is incorporating a perfect muting circuit which does not make a shock noise so that a shock noise design in the set transitional state can be made easily when used together with its standby function.

In addition, it is incorporati

AN7551Z Features

* Pin arrangement which does not allow the input/output patterns to intersect each other so that it is possible to make a pattern design on a one-sided printed circuit board.

* Incorporating various protection circuits (thermal protection, short-circuit to VCC , short-circuit to VCC
