Overview
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 incorporating various protective circuits to protect the IC from destruction by GND-open earth short-circuiting and power supply surge which are the important subject of power IC, and the IC will largely contribute to a high reliability design of equipment.

15) Seating plane s 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 in VCCopened, short-circuit to GND, short-circuit to GND in GND-opened, over voltage, power supply surge, and ASO protection, etc.
) • Incorporating standby function (shock noise-free at STBon/off) • Incorporating standby function (shock noise-free at Mute-on/off) • External components reduction • Provided with beep sound input pin • Equipped with auxiliary sound input pin • Inverted pin layout of AN7550NZ on right and left pins HZIP025-P-0980 s Applications • Car stereo, miniature audio component, karaoke and other audio equipment.
