LV49157V
Overview
The LV49157V is a 15W per channel stereo digital power amplifier that takes analog inputs. The LV49157V 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.
Features
BTL output, class D amplifier system
Unique SANYO-developed feedback technology achieves superb audio quality
High-efficiency class D amplifier
Soft muting function reduces impulse noise at power on/off
Full complement of built-in protection circuits : over current protection, thermal protection, and low power supply
voltage protection circuits
Built in Power limiter
Built in Headphone Amplifier
