LMH6704 650 MHz Progammable Gain Buffer

The LMH™6704 is a very wideband, DC coupled progammable gain buffer designed specifically for wide dynamic range systems requiring exceptional signal fidelity. The LMH6704 includes on chip feedback and gain set resistors, simplifying PCB layout while providing user programmable gains of +1, +2 and −1 V/V. The LMH6704 provides a disable pin, which places the .
