ICs for Audio Common Use

s Overview

The AN7168 is an integrated circuit designed for low

distortion, low noise and low power dissipation audio set

of 5.8W (13.2V, 4

Ω) 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 pro-

tection circuits are built in.
