LV4924VH
Overview
The LV4924VH is a 2-channel 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.
