Parasitic Feedback Parameters (Approximate)

The quotation of these parameters does not indicate that

elaborate decoupling arrangements are required, the

amplifier has been designed specifically to avoid this

requirement. The parameters have been given so that the

necessity or otherwise of further decoupling, may become a

matter of calculation rather than guesswork.
