LV4900H
Overview
The LV4900H is a 10W per channel stereo digital power amplifier that takes analog inputs. The LV4900H uses unique
SANYO-developed feedback technology to achieve excellent audio quality despite being a class D amplifier and can be
used to implement high quality flat display panel (FDP) based systems.
Features
• Supports circuit designs that do not require output LC filters
• BTL output, class D amplifier system
• Unique SANYO-developed feedback technology achieves superb audio quality
• High-efficiency class D amplifier
• Soft 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
• Internal oscillator frequencies : channel 1 = 325kHz, channel 2 = 300kHz
Functions
• 10W output (At VD = 12V, RL = 8Ω, THD + N = 10%)
• 15W output (At VD = 12V, RL = 4Ω, THD + N = 10%)
• Efficiency
: 88% (VD = 12V, RL = 8Ω, fin = 1kHz, PO = 10W)
• Low THD + N : 0.15% (VD = 12V, RL = 8Ω, fin = 1kHz, PO = 1W, Filter : AES17)
• Noise
: 100
