描述 Description

■ Overview
The AN7195K 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 AN7195K is pin compatible with the AN7190NK (dual 20 W), so that the identical pattern design is allowed for high-class types as well as popular types.■

特性 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)
