AN7555NZ
BTL output power IC for car audio
s Overview
The AN7555NZ is an audio power IC developed as
the sound output of car audio (35 W × 4-channel). It has
realized the voltage gain of 40 dB based on the AN7560Z
(voltage gain: 34 dB). A capacitor and resistor to stop
oscillation are built in between the output pin and GND so
that a space saving of set is possible. Also, it incorpo-
rates 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
short circuit 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.
s 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
protection, short circuit to VCC , VCC-open short circuit
to VCC , short circuit to GND, GND-open short circuit to
GND, overvoltage, power supply surge, and ASO, etc.)
• Built-in standby function (shock-noise free at STB-on/
off)
• Built-in muting function (shock-noise free at Mute-on/
off)
• External components reduction
• Provided with beep sound input pin
• Equipped with auxiliary sound input pin
• Voltage gain: 40 dB
(AN7560Z/AN7561Z: Voltage gain: 34 dB)
s Applications
• Car stereo, miniature audio component, karaoke and
other audio equipment
