Overview

The LV4920H is a 2-channel BTL full-bridge driver for digital power amplifiers. It requires a PWM modulator IC in the previous stage. This IC is a power cell that takes in PWM signals as an input and is used to form a digital amplifier system for TVs, amusement equipment, and other such systems.

Features

• BTL output, class D amplifier system

• High-efficiency class D amplifier

• Muting function reduces impulse noise at power on/off

• Full complement of built-in protection circuits: overcurrent protection, thermal protection, and low power supply voltage protection circuits

• Built-in bootstrap diodes

Application

• TV sets (PDP/LCD)

• Amusement equipment (pinball or pinball-slot-machines)

• Home audio equipment (mini-/micro-audio systems)

• Home theater equipment
