Hello friends,
I need to know about the SDA and SCL pins on AD5933 as I did not find any holes or grooves to connect it to other hardware.
Please reply with detailed explanation.
Regards,
Nikhil.

A quick Google for that part number finds this
http://www.analog.com/static/imported-files/data_sheets/AD5933.pdf
this clearly shows the SDA and ACL pins are pins 15 and 16 of the chip resp.
If your talking about this Analog Devices: EVAL-AD5933EBZ Evaluation Board for the AD5933 1 MSPS 12-Bit Impedance Converter Network Analyzer
then it is also clearly shown on page 36 (Pins 15 and 16) going to page 37 MPU pins 16 and 15 but no I/O connector
This is all clearly shown in the documentation provided so im not sure what your looking for as I expect you have already found this as part of your initial investigation
Please explain what you trying to do, perhaps then I can advise better
Thanks
Hi peter,
Thanks for your response.
I want to find out unknown impedance value using EVAL-AD5933EBZ board.
But its confusing that how to measure unknown impedance of a sensor using EVAL-AD5933EBZ board.
We have to specify the resistors or capacitor values in EVAL-AD5933EBZ board software. Then only mid-point gain is calculated and frequency sweep is enabled.
Then how can we give resistor or capacitor values for a complex sensor ???
In order to analyse the impedance characteristics with frequency, magnitude and phase ?
