AN7164
30 W BTL audio power amplifier
n Overview
The AN7164 is an integrated circuit designed for 30
W (V
CC
= 21 V, 8 W ) output power amplifier. High power
output (BTL 30 W), low distortion and low noise are re-
alized. High reliability is obtained due to various kinds
of protectors built in. Furthermore, on-off of output is
possible from standby terminal.
n Features
• High power output
• Low distortion, Low noise
• Low shock noise when power supply is turned-on, off
• Built-in standby function
• Built-in protection circuits
(Temperature, Overcurrent, Load short circuit, Output -
GND short circuit)
n Applications
• Stereo, Karaoke, TV
