Dual 20 W BTL Power IC for Car Audio
s Overview
The AN7198Z is an audio power IC developed for the
sound output of car audio (Dual 20 W).
A capacitor and a resistor between the output pin and
GND to stop oscillation are built-in so that a space saving
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 important subjects of power IC protection, and the IC
will largely contribute to a high reliability design of equip-
ment.
