LV49152V
Overview
Class-D Audio Power Amplifier
BTL 15W
×
2ch
The LV49152V is a 15W per channel stereo digital power amplifier that takes analog inputs. The LV49152V 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.
