Class-D Audio Power Amplifier
BTL 10W×2ch
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, R = 8Ω, THD + N = 10%)
L
• 15W output (At VD = 12V, R = 4Ω, THD + N = 10%)
L
• Efficiency
: 88% (VD = 12V, R = 8Ω, fin = 1kHz, P = 10W)
L O
• Low THD + N : 0.15% (VD = 12V, R = 8Ω, fin = 1kHz, P = 1W, Filter : AES17)

Functional Descriptions
System Standby
The bias levels are turned on and off under control of the high/low state of the STBY pin. When the STBY pin is low,
the bias levels will be turned off, and when that pin is high, the bias levels will be applied.
Mute Function
The mute function is provided mainly to mute the output so that impulse noise will not appear in the output when the
power supply is being turned on.
(1) Output Muting
The output PWM signal can be turned on or off by setting the MUTE pin high or low. When the MUTE pin is low, the
internal oscillator is stopped. This oscillator operates at all times that the MUTE pin is high.
(2) Power On Sequence
Applications should provide a power-on muting period of at least 500ms to minimize impulse noise.
