The LMH6704MA/NOPB(购买请点击) is a very wideband, DC coupled selectablegain buffer designed specifically for wide dynamic rangesystems requiring exceptional signal fidelity. The LMH6704includes on chip feedback and gain set resistors, simplifyingPCB layout while providing user selectable gains of +1, +2and −1 V/V. The LMH6704 provides a disable pin, whichplaces the amplifier in a high output impedance, low powermodeLMH6704MA/NOPB(购买请点击). The Disable pin may be allowed to float high.
With a 650 MHz Small Signal Bandwidth (AV = +1), fullpower gain flatness to 200 MHz, and excellent DifferentialGain and PhaseLMH6704MA/NOPB(购买请点击), the LMH6704 is optimized for video applications.High resolution video systems will benefit from theLMH6704’s ability to drive multiple video loads at low levelsof differential gain or differential phase distortion.
The LMH6704 is constructed with National’s proprietary highspeed complementary bipolar process using National’sproven current feedback circuit architecturesLMH6704MA/NOPB(购买请点击). It is availablein 8-Pin SOIC and 6-Pin SOT23 packages.
