n Overview
The AN7169 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 volt-
age protection circuits are built in.
n 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
