■ Overview

The AN7195Z is an audio power IC developed for the sound output of car audio (dual 15 W).

It is incorporating various protection circuits 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 industrys first excellent 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, the AN7195Z is pin compatible with the AN7136Z (dual 20 W), so that the identical pattern design is allowed for high-class types as well as popular types.

■ Features

• Built-in various protection circuits (realizing high break

down voltage against destruction )

Power supply surge breakdown voltage of 100 V or more

Ground-open breakdown voltage of 14 V or more

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

standby 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 (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

• High sound quality design

• Pin compatible with the AN7136Z (dual 20 W)

■ Applications

• Car audio
