The Electrical Characteristics and Typical Performance plots specify an RF of 300Ω, a gain of +2V/V and ±5V power supplies (unless otherwise specified).

LMH6714, LMH6720 LMH6722, LMH6722-Q1 www.ti.com SNOSA39G – NOVEMBER 2002 – REVISED APRIL 2013 In the Figure 32 and Figure 33 charts, the recommended value of RF is depicted by the solid line, which starts high, decreases to 200Ω and begins increasing again. The reason that a higher RF is required at higher gains is the need to keep RG from decreasing too far below the output impedance of the input buffer.

While disabled the LMH6720 quiescent current is approximately 500μA. Because of the pull up resistor on the disable circuit the ICC and IEE currents are not balanced in the disabled state. The positive supply current (ICC) is approximately 500μA while the negative supply current (IEE) is only 200μA.

Performance degrades as the loading is increased, therefore best performance will be obtained with back terminated loads. The back termination reduces reflections from the transmission line and effectively masks capacitance from the amplifier output stage.

An equalizer can be made to pre emphasize the higher frequency components so that the final signal has less distortion. This process can be done at either end of the cable.
