Panasonic AN7158N Datasheet
ICs for Audio Common Use
■ Overview
The AN7158N is an integrated circuit designed for
power amplifier of 7.5W (16V, 4Ω) output with low noise
and low distortion, and it suits TV set with multi-sound.
Stereo operation is enabled due to incorporating two
amplifiers on one chip. 12-pin SIL package enabled compact and high-densely mounted set.
■ Features
•
Incorporating protection circuits (surge, thermal protec-
tion and etc.)
•
Automatic operating point stabilizer circuit
•
Low distortion, low 1/f noise
•
Low shock noise from power ON/OFF operation
•
Better channel separation
•
Fewer external components
