one, there is little to be gained from choosing resistor R1

value below 200, for it would only result in increased power

dissipation and potential signal distortion. Above 200, the

bandwidth response will develop some peaking (for a gain of

one), but substantially higher R1 values may be used for

higher voltage gains, such as up to 1k at a gain of four

before peaking will develop.

Applications Information

Capacitance Considerations

As with many high bandwidth amplifiers, the EL2142 prefers

not to drive highly capacitive loads. It is best if the

capacitance on V

is kept below 10pF if the user does not

OUT

want gain peaking to develop. The V node forms a

potential pole in the feedback loop, so capacitance should

be minimized on this node for maximum bandwidth.

Gain Equation

The amount of capacitance tolerated on any of these nodes

in an actual application will also be dependent on the gain

setting and the resistor values in the feedback network.
