ICs for Audio Common Use
AN7190NK, AN7190NZ
Dual 20 W BTL power amplifier
s Overview
The AN7190NK and the AN7190NZ are audio power
ICs developed for the sound output of car audio (dual 20
W). It is incorporating various protective circuits to pro-
tect the IC from destruction by GND-open, short circuit
to GND and power supply surge which are the important
subject of power IC protection, so the IC will largely
contribute to a high reliability design of equipment. Also,
it is incorporating a perfect muting circuit which is free
from shock noise, so that a shock noise design under the
set transient condition can be made easily using together
with its standby function.
s Features
• BTL 20 W × 2-channel (4 Ω), GV = 40 dB
• Built-in various protection circuits (thermal protection,
short circuit to VCC and short circuit to GND, VCC-open
short circuit to VCC , GND-open short circuit to GND,
overvoltage and supply surge, and ASO, etc.)
Especially, the supply surge breakdown voltage is 100
V or more.
GND open breakdown voltage is 16 V or more.
• Built-in standby function
Free from shock noise at 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 .
Attack time, recovery time are 50 ms or less.
• Reduction in external components
It eliminates the need for NF and BS electrolytic ca-
pacitors.
Muting function is not required, and power supply choke
coil is unnecessary.
• Provided with beep sound input pin
• 2 Ω load guaranteed
s Applications
• Car audio
