AN7195Z
Dual 15 W BTL power IC for car audio
s 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 pro-
tect the IC from destruction by GND-open short-circuit
to GND and power supply surge which are the most im-
portant subjects of power IC protection, and the IC will
largely contribute to a high reliability design of equip-
ment.
It is also incorporating the industry's 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.
s 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 ca-
pacitors,
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)
