LV4912GP
Overview
Features
Functions
The LV4912GP is analog input type digital power amplifier with 2W × 1 channel. By using an original feed back
technology, it improves sound quality through it is class-D power amplifier and the LC filter in the output stage can be
deleted as application.
• Enabling output LC filter-less.
• Class-D amplifier system of the output BTL type.
• Improve the sound quality by the use of original feedback technology.
• Realized high efficiency class-D amplifier.
• Reduce the pop sound at ON/OFF state by the use of soft mute function.
• Full complement of built-in protection circuits : over current protection, thermal protection, and low power supply
• Internal oscillation frequency : 280kHz
• Output power
• THD + N
• Noise
• Package
voltage protection circuits.
