... This ampli- fier uses current-mode feedback to achieve more bandwidth at a given gain than conventional operational amplifiers. Designed for closed- loop gains of ±1 to ±8, the EL400C has a 200MHz -3dB bandwidth (A = +2), and 12ns settling to 0.05% while consuming only 15mA of V supply current ...

... The EL400C has a unity gain buffer from the non-invert- ing input to the inverting input. The error signal of the EL400C 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 ...

... Capacitance at the output node will reduce stability, eventually resulting in peaking, and finally oscillation if the capacitance is large enough. The design of the EL400C allows a larger capacitive load than comparable products, yet there are occasions when a series resistor before the capacitance may be needed. Please refer to the graphs to determine the proper resistor value needed ...
