AN7190NK, AN7190NZ

Dual 20 W BTL power amplifier

■ 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 pro­tect 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.

■ Features

• BTL 20 W × 2-channel (4 Ω), GV = 40 dB

• Built-in various protection circuits (thermal protection,

short circuit to V
short circuit to V
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 ca­pacitors.
Muting function is not required, and power supply choke
coil is unnecessary.

• Provided with beep sound input pin

• 2 Ω load guaranteed
