■ Overview

The AN7196K is an audio power IC developed for the sound output of car audio (dual 15 W). Especially, this circuit has solved the problem of heat radiation design inherent to a single chip IC with 4-channel audio ouputs and realized a corresponding space saving at the same time.

■ Features

? Built-in various protection circuits (realizing high breakdown voltage against destruction )

Power supply surge breakdown voltage of 100 V or more

Ground open breakdown voltage of 16 V or more

? Built-in standby function (free from shock noise at standby on/off)

? Built-in muting function (the industrys first)

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

? Space saving design is possible with a small size package

A heat radiation design that has been a problem particularly in a 4-ch. single chip IC can be done by the conventional method.

? Reduction in external components (parts reduction to half compared with the AN7176K)

It eliminates the need for NF and BS electrolytic capacitors,

Muting function is unnecessary

Power supply choke coil is unnecessary

? Provided with beep sound input pin

? Pin compatible with the AN7191NK (dual 20 W)

■ Applications

? Car audio
