LV4900H

www.DataSheet.co.kr Ordering number : ENA0097 Bi-CMOS LSI LV4900H 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) Any and all SANYO Semiconductor Co.,Ltd. products described or contained herein are, with regard to "standard application", intended for the use as general electronics equipment (home appliances, AV equipment, communication device, office equipment, ...
