Wayne/tech/anyone know how to measure the output impedence of a line driver? I build my own, and before I sell them with a wrong spec (I've calculated the output impedance according to formulas) and it's very low (lower than the pld1's 30ohm..) I just don't wanna missrepresent it if I'm wrong.
any help would be great. thanx

I think the only way is to measure the output voltage with a 1000 ohm load, and then measure with a 500 ohm load. Then you could calculate the output impedance by the change.
