AN7560Z
BTL output power IC for car audio
■ Overview
The AN7560Z is an audio power IC developed as the
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 possible. Also, it incorporates a perfect muting circuit without 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 various protection circuits to protect the IC from destruction by GND-open-shortcircuit to ground and power supply surge which are the important subject of power IC
protection. This IC will largely contribute to a high reliability design of the equipment.
■ Features
• 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
