ICs for Audio Common Use

AN7190NK, AN7190NZ

Dual 20 W BTL power amplifier

■ Overview

AN7190NK

Unit : mm

11.3±0.3

7.7±0.3

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.

■ Features

AN7190NZ

Unit : mm

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

• Built-in various protection circuits (thermal protection,

short circuit to V_CCand short circuit to GND, V_CC-open

short circuit to V_CC, GND-open short circuit to GND,

overvoltage and supply surge, and ASO, etc.)

Especially, the supply surge breakdown voltage is 100

V or more.

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

■ Applications

• Car audio
