... The bandwidth and slew rate of the EL2020 are relatively independent of the closed loop gain taken. The 50MHz bandwidth at unity gain only reduces to 30MHz at a gain of 10. The EL2020 may be used in most applications where a conventional op amp is used, with a big improvement in speed power product. ...

... The EL2020 has a unity gain buffer similar to the EL2003 from the non-inverting input to the inverting input. The error signal of the EL2020 is a current flowing into (or out of) the inverting input. A very small change in current flowing through the inverting input will cause a large change in the output voltage ...

... Resistor Value Selection and Optimization The value of the feedback resistor (and an internal capacitor) sets the AC dynamics of the EL2020. A nominal value for the feedback resistor is 1kΩ, which is the value used for production testing. This value guarantees stability. For a given gain, the bandwidth may be increased by decreasing the feedback resistor and, conversely, the bandwidth will be decreased by increasing the feedback resistor ...

... With 30mA of output drive and low output impedance, driving one to three 75Ω double terminated coax cables with one EL2020 is practical. Since it is easy to set up a gain of +2, the double matched method is the best way to drive coax cables, because the impedance match on both ends of the cable will suppress reflections ...
