AN7194

Manufacturer Part Number
AN7194
Description
Dual BTL 50 W single power supply class-H power amplifier IC
Manufacturer
Panasonic Semiconductor
Datasheet
ICs for Audio Common Use
AN7194K, AN7194Z
Dual BTL 50 W single power supply class-H power amplifier IC
ply, 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 mar-
ket-available, and it is possible to make a low consump-
tion power system. Also, the AN7194K and AN7194Z
are incorporating various protection circuits, so that those
ICs contribute to the high reliability design of set.
karaoke are other audio equipment
Incorporating various protection circuits :
Thermal protection, load short-cirucit, short circuit to
V
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
Miniature audio component, CD player radio cassette,
Overview
Features
Applications
The AN7194K and AN7194Z are single power sup-
CC
and short circuit to GND, overvoltage.
