I am designing a signal buffer/splitter that takes analog signals (+/- 5V) (<< 30kHz) from a DB-25 cable and splits them among several outputs, also DB-25. Essentially each output is an exact copy of the input signals. At the moment, I am using TL074 chips for the outputs with one op-amp per output signal. The opamps are set up as "voltage followers" (inverting input tied to output) and the output is tied directly to the output pin with no extra circuitry.
My question is whether or not I need any more circuitry to drive the signals down the DB-25 or if the op-amps will suffice. This is the first time I've dealt with signal buffers and unfortunately they don't teach you anything practical in school (at least in my experience...)
If it's at all confusing I can try to upload schematics, but it's straight forward so I figured I could get away without any schematics.
