Dual 7.5W Audio Power Amplifier Circuit
s
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 com-
pact and high-densely mounted set.
