LA4801V
Headphone Stereo Power Amplifier
Overview
The LA4801V is a headphone stereo power amplifier for
portable CD and MD players. It features a high signal-to-
noise ratio, a high ripple rejection ratio, low distortion,
and low current drain.
Functions
• Headphone stereo power amplifier
• Power switch
• Muting switch
• Center amplifier switch
Features
• High signal-to-noise ratio (96 dB typical at 7 µV)
• High ripple rejection ratio (76 dB typical)
• Low current drain (4.8 mA typical)
• Low power consumption achieved through the use of a
dual power supply system.
• No electrolytic capacitors required for the outputs.
• Ultraminiature package (SSOP-16)
