Dual 20 W BTL power IC for car audio

■ Overview

Unit : mm

The AN7199Z is an audio power IC developed for the

sound output of car audio (dual 20 W).

A capacitor and a resistor to stop oscillation are built

in between the output pin and GND so that a space sav-

ing of set is possible. Also, it is incorporates an industry's

first superior muting circuit which is free from shock

noise, so that a shock noise design under the set transient

condition can be made easily when the muting circuit is

used together with its standby function.

In addition, it is incorporating various protective cir-

cuits to protect the IC from destruction by GND-open

short-circuit to GND and power supply surge which are

the most important subjects of power IC protection, and

the IC will largely contribute to a high reliability design

of equipment.

■ Features

• Built-in various protection circuits (realizing high break-

down voltage against destruction)

Power supply surge breakdown voltage of 80 V or more

Ground open breakdown voltage of 16 V or more

• Built-in standby function (free from shock noise when

STB-on/off)

• Built-in muting function

Free from shock noise at mute-on/off

• Adapting attenuator method so that abnormal sound due

to waveform deformation is not generated

Attack time, recovery time of 50 ms or less

• Reduction in external components

No CR for oscillation stop is required

It eliminates the need for NF and BS electrolytic ca-

pacitors

Muting function is unneccesary

Power supply choke coil is unnecessary

• Provided with beep sound input pin

• High sound quality design

■ Applications

• Car audio
