LV4924VH
Bi-CMOS IC
Class-D Audio power Amplifier
Power cell BTL 10W×2ch
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.
Features
• BTL output, class D amplifier system
• High-efficiency class D amplifier
• Muting function reduces impulse noise at power on / off
• Protection circuits incorporated for over-current, thermal, supply voltage drop, output offset detector
• Built-in bootstrap diodes
Specification
• Output 15W (VD=16V, RL=8Ω, fIN=1kHz, AES17, THD+N=10%)
• Output 10W (VD=13V, RL=8Ω, fIN=1kHz, AES17, THD+N=10%)
• Efficiency : 89% (VD=13V, RL=8Ω, fIN=1kHz, PO=10W)
• THD+N
: 0.1% (VD=13V, RL=8Ω, fIN=1kHz, PO=1W, Filter: AES17)
