Panasonic AN7164N Datasheet
ICs for Audio Common Use
■ Overview
The AN7164N is an integrated circuit designed for 47W
(V
CC
= 26.4V, 8Ω) output power amplifier. High power
output (BTL 47W), low distortion and low noise are realized. High reliability is obtained due to same kinds of protectors built in. Furthermore, ON/OFF is enabled even if
power is supplied to power supply pin by stand-by circuit.
■ Features
•
High output power
•
Low distortion, low noise
•
Low shock noise from power ON/OFF operation
•
Incorporates stand-by circuits
•
Incorporates protection circuits
