Overview
Class-D Audio Power Amplifier BTL 10W×2ch
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 : 100µVrms (Filter : A-weight)
