AN7164
30 W BTL audio power amplifier
■ Overview
The AN7164 is an integrated circuit designed for 30
W (V
= 21 V, 8 Ω) output power amplifier. High power
CC
output (BTL 30 W), low distortion and low noise are realized. High reliability is obtained due to various kinds
of protectors built in. Furthermore, on-off of output is
possible from standby terminal.
■ 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)
■ Applications
• Stereo, Karaoke, TV
