Bi-CMOS LSI
Class-D Audio Power Amplifier
BTL 2W × 2ch
Overview
LV4910T is a stereo digital amplifier for portable equipment, for example notebook-PC, portable DVD and portable
mini-speakers. It is characterized by the use of an original feedback technology to improve sound quality though it is
Class-D amplifier, and does not need the LC filter in the output stage.
Features
• D-class high-efficiency amplifier
• Low pop sound at SW changeover
• Differential input type
Functions
• 2W stereo digital power amplifier
• Standby switch
• Mute switch
• Various protective circuits (over-current protective, thermal protective, and under-voltage circuits) incorporated
