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
