Overview
The LA4805V is a power IC developed for use in stereo headphones. It includes low frequency enhancement, beep function and output control circuits on-chip. Furthermore, the LA4805V realizes a high S/N ratio, a high ripple exclusion ratio, and low current drain.

FEATUREs
• Low current drain (8.3 mA typical)
• High S/N ratio (90 dB typical, 13 µV)
• High ripple exclusion ratio (75 dB typical)
• No output electrolytic capacitors required
• Ultra-miniature package (SSOP-30)

Functions
• Stereo headphone power amplifier
• Low frequency enhancement (L.BOOST)
• Beep amplifier
• Output suppression circuit (PVSS)
• Power switch
• Muting switch
