ICs for Audio Common Use
AN7560Z
BTL output power IC for car audio
sound output of car audio (35 W by 4-ch.). A capacitor
and resisitor to stop oscillation are built in between the
output pin and GND so that a space saving of set is pos-
sible. Also, it incorporates a perfect muting circuit with-
out shock noise so that a shock noise design under the set
transient condition can be made easily when used together
with its standby function. In addition, it incorporates var-
ious protection circuits to protect the IC from destruc-
tion by GND-open-shortcircuit to ground and power sup-
ply surge which are the important subject of power IC
protection. This IC will largely contribute to a high reli-
ability design of the equipment.
A pattern layout in which input and output pattern do
not intersect each other on single-sided printed circuit
board is possible.
Incorporating various protection circuits (temperature,
shortcircuit to V
shortcircuit to GND, GND-open short circuit to GND,
overvoltage, power supply surge, and ASO, etc.)
Built-in standby function (shock noise-free when STB-
on/off)
Built-in muting function (shock noise-free when Mute-
on/off)
External components reduction
Provided with beep sound input pin
Equipped with auxiliary sound input pin
