Panasonic AN7168 Datasheet

ICs for Audio Common Use

■ Overview

The AN7168 is an integrated circuit designed for low
distortion, low noise and low power dissipation audio set
of 5.8W (13.2V, 4Ω) output. Stereo operation is enabled
due to incorporating two amplifiers on one chip. 12-pin
SIL package enabled compact and high integrated set.
Thermal protection, short protection and excessive pro­tection circuits are built in.
