ICs for Audio Common Use

AN7194K, AN7194Z

Dual BTL 50 W single power supply class-H power amplifier IC

■ Overview

The AN7194K and AN7194Z are single power sup­ply, BTL, audio class-H power amplifier ICs. A class-H
power amplifier can be made up when this ICs are used in
combination with the AN7077Z which is separately mar­ket-available, and it is possible to make a low consump­tion power system. Also, the AN7194K and AN7194Z
are incorporating various protection circuits, so that those
ICs contribute to the high reliability design of set.

■ Features

• Incorporating various protection circuits :

Thermal protection, load short-cirucit, short circuit to
V

and short circuit to GND, overvoltage.

CC

• Built-in stand-by function

(Free from shock noise when standby turns-on/off)

• Built-in muting function

Free from shock noise at mute-on/off
Adapting attenuator method so that abnormal sound is
not generated due to waveform deformation
Attack time, recovery time are 20 ms or less

• Reduction in external components

NF and BS electrolytic capacitors are needless
RF electrolytic capacitor is needless
External muting function is needless

• OR output terminal is provided

• Designed for headphone use

• The AN7194K is of a 16-pin and the AN7194Z is of a

15-pin package
