AN7199Z
Dual 20 W BTL power IC for car audio
s
Overview
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
