AD9834: I have been going through the datasheet and this seems perfect device for my
needs, however i did not see explicit mentioning of measuring inductive
reactance. I am interested in setting up a test jig for 0.5H coils with a DCR
of about 30 to 40 ohms (ferrite core). It seems to me that this IC can perform
the task however I would like some sort of confirmation prior to purchase.
2nd question regarding the evaluation package. I've noticed that it comes
complete with PC software to conduct tests. I will be interested in lowering
the minimal measurable impedance by adding the buffer as suggested in the
datasheet, can I use the software to read these values or does it, from any
reason, support only values above 1Kohm?
In case of 470uH the measurement results looks fine - please see attached.
Please note that the limitation is not due to the software but the hardware.
This limitation has been overcome by using external buffers, refer to UG-364,
