Overview
The LV49157V is a 15W per channel stereo digital power amplifier that takes analog inputs. The LV49157V uses
unique Our 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 Our 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
Functions
