Bi-CMOS IC
LV4920H Class-D Audio Power Amplifier
Power Cell BTL 15W×2CH, 10W×2CH
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.
Application
• TV sets (PDP/LCD)
• Amusement equipment (pinball or pinball-slot-machines)
• Home audio equipment (mini-/micro-audio systems)
• Home theater equipment
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
Specification
• Output 1=10W/ch, THD+N=10%, 8Ω Load, 1kHz, AES17, VD=13V
• Output 2=15W/ch, THD+N=10%, 8Ω Load, 1kHz, AES17, VD=16V
• High efficiency 85% or larger (Condition: 8Ω Load)
• THD+N<0.1% 1W/1kHz/8Ω Load (Filter: AES17)
• Package: HSOP36
