AN7561Z
BTL output power IC for car audio
n Overview
The AN7561Z 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 sav-
ing 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 func-
tion. 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.
n 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 pro-
tection, short-circuit to V

opened, 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 STB-
on/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 AN7560Z on right and left pins
n Applications
• Car stereo, miniature audio component, karaoke and
other audio equipment.
