Technical content

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 pro- tection circuits are built in. n Features
