lize the loop. The 100Ω resistor at the EL2008C output

(R2) to the -12V supply, insures that the EL2008C

sources current even when the output voltage is at 0V.

This is necessary to achieve the excellent differential

gain and phase values. More information about driving

cables can be found in the EL2003 data sheet. See the

EL2020 data sheet to learn more about using it as a

multiplexer.

The EL2008C can drive 15 double matched 75Ω cables.

If the EL2008C is used within an op amp feedback loop

the output levels are independent of loading. The circuit

below accepts 1 of 2 inputs and drives 15 cables. Pin 8 of

the EL2020 (Disable) is used to multiplex between the

inputs and can be easily expanded to accept more inputs.

The circuit as shown when fully loaded has differential

phase <0.1° and differential gain <0.1%. The 100Ω

resistor at the EL2008C input (R1) is necessary to stabi-
