LV49152V
Bi-CMOS LSI
Class-D Audio Power Amplifier
BTL 15W × 2ch
Overview
The LV49152V is a 15W per channel stereo digital power amplifier that takes analog inputs. The LV49152V 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
• 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 : over current protection, thermal protection, and low power supply
voltage protection circuits
• Built in Power limiter
Functions
• Power : 15W × 2ch output (VD = 15V, RL = 8Ω, fin = 1kHz, AES17, THD + N = 10%)
• Efficiency : 93% (VD = 15V, RL = 8Ω, fin = 1kHz, PO = 15W)
• THD + N : 0.08% (VD = 15V, RL = 8Ω, fin = 1kHz, PO = 1W, Filter : AES17)
• Noise : 90µVrms (Filter : A-weight)
• Package SSOP44J (275mil)
