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.
s Features
• Low voltage operation : VCC = 1.8V to 4.5V
• Reduced voltage operation is available.
• Low pop noise when supply voltage is switched ON
and OFF
• Stereo drive of 4Ω (speaker) to 32Ω (headphone) load
is possible.
