AN7168
Dual 5.8W Audio Power Amplifier Circuit
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, 4â¦) 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.
s Features
⢠Highly stable operation
⢠Low distortion
⢠Low quiescent current
⢠Low noise
⢠Low shock noise from power ON/OFF operation
⢠Built-in muting circuit
⢠Fewer external components
⢠Incorporating protection circuits
