AN7194K Datasheet, PDF (1/4 Pages) Panasonic Semiconductor – Dual BTL 50 W single power supply class-H power amplifier IC

ICs for Audio Common Use
AN7194K, AN7194Z
Dual BTL 50 W single power supply class-H power amplifier IC
s Overview
The AN7194K and AN7194Z are single power sup-
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.
s Features
• Incorporating various protection circuits :
Thermal protection, load short-cirucit, short circuit to
V_CC and short circuit to GND, overvoltage.
• 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
s Applications
• Miniature audio component, CD player radio cassette,
karaoke are other audio equipment
