Hi,
To protect an op amp's output from a cable capacitance, we usually put an output protection resistor (around 47ohms) to prevent HF instability.. Am I right?
My question is, in a piece of gear, if an op amp's output goes to a pot or whatever through a 1ft shielded cable (more or less) should we put an output protection resistor to the op amp or buffer?
Thanks
