Bi-CMOS LSI

Class-D Audio Power Amplifier

BTL 15W

× 2ch

LV49152V

Overview

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.

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
