LM3886是美国NS公司(国家半导体公司)最近推出的新一代大功率、免调试型Hi～Fi线性集成功放,该集成电路设计额定输出功率在±35V电源、4Ω负载时为68W,瞬间峰值功率可达150W。在电源电压±10～42V之间均能正常工作,且在5Hz一100KHz内线性度良好,总谐波失真率≤0.003％,信噪比达110dB,因而在音质及力度上超过了以往任何一种线性集成功放,并具有过压、欠压、过载、短路、超温、开机防冲击等完善的保护功能。特别适合用来制作大功率Hi—Fi功放及有源音箱,由于外围元件少,且免调试,容易制作,装上即可使用。
The LM3886 is a new generation of high-power, debug-free, Hi-Fi linear integrated amplifier recently introduced by NS Corporation of the United States (National Semiconductor Corporation). The integrated circuit design is rated for ± 35V output power and 68W at 4Ω load. Instantaneous peak power Up to 150W. In the power supply voltage ± 10 ~ 42V between the normal work, and in a 5Hz a 100KHz good linearity, total harmonic distortion rate ≤ 0.003%, signal to noise ratio of 110dB, which in sound quality and intensity over any of the past Integrated linear amplifier, and has over-voltage, under-voltage, overload, short circuit, over-temperature, boot anti-shock and other sound protection. Particularly suitable for the production of high-power Hi-Fi amplifier and active speakers, due to fewer external components, and debugging-free, easy to make, can be installed to use.
