Dual 5.8W Audio Power Amplifier Circuit
■ Overview
Unit : mm
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 voltage protection circuits are built in.
