AN7561Z
BTL output power IC for car audio
■ 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 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.
■ 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
