Class-D Audio Power Amplifier BTL 10W×2ch
Package HSOP 36 Pin Type
LV4900H overview
The LV4900H is a Class-D Audio Power Amplifier BTL 10W×2ch made by Sanyo, supplied in an HSOP 36 Pin Type package. The absolute maximum ratings table on this page lists the 5 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the LV4900H pinout and maximum ratings, with the full datasheet PDF to preview below or download.
The LV4900H is a 10W per channel stereo digital power amplifier that takes analog inputs. The LV4900H 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.
