LV4901H
Overview
Buit-in 80mW Headphone amplifier
BTL 10W×2ch Crass-D Audio Power Amplifier
The LV4901H is a 10W per channel stereo digital power amplifier that takes analog inputs. The LV4901H uses unique
SANYO-developed feedback technology to achieve excellent audio quality despite being a class D amplifier and can be
used to implement high quality flat display panel (FDP) based systems.
