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
