ICs for Audio Common Use
AN7118S
Low Voltage Dual 35mW Audio Power Amplifier Circuits (BTL 300mW)
s
Overview
The AN7118S is the ICs designed for power amplifier of
low voltage operated compact radio and stereo tape
recorder. Stereo operation is enabled due to incorporat-
ing two amplifiers on one chip. Miniaturization of cassette
and high integration is realized due to SOP package.
