LV4912GP中文资料三洋数据手册PDF规格书

Overview

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.

特性 Features

• 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 voltage protection circuits.

• Internal oscillation frequency : 280kHz

Functions
