BTL output power IC for car audio

■ Overview

Unit: mm

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.

■ 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 V_CC, V_CC-open short circuit

to V_CC, 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)

■ Applications

• Car stereo, miniature audio component, karaoke and

other audio equipment
