Dual 15 W BTL power IC for car audio

s 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.

In addition, it is incorporating various protection 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.

It is also incorporating the industry's first perfect

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.

The AN7196K is pin compatible with the AN7191NK

(dual 20 W), so that the identical pattern design is allowed

for high-class types as well as popular types.

s 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 industry's 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)

s Applications

• Car audio
