LMH6739中文资料非常宽带、低失真三路视频缓冲器数据手册TI规格书

描述 Description

The LMH6739 is a very wideband, DC coupled monolithic selectable gain buffer designed specifically for ultra high resolution video systems as well as wide dynamic range systems requiring exceptional signal fidelity. Benefiting from current feedback architecture, the LMH6739 offers gains of −1, 1 and 2. At a gain of +2 the LMH6739 supports ultra high resolution video systems with a 400 MHz 2 VPP3 dB Bandwidth. With 12-bit distortion level through 30 MHz (RL = 100Ω), 2.3nV/√Hz input referred noise, the LMH6739 is the ideal driver or buffer for high speed flash A/D and D/A converters. Wide dynamic range systems such as radar and communication receivers requiring a wideband amplifier offering exceptional signal purity will find the LMH6739 low input referred noise and low harmonic distortion make it an attractive solution. The LMH6739 is offered in a space saving SSOP package.
