About Evaluation board AD5933

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.

Hello Nikhil,
Welcome to the element14 Community, we hope you enjoy it! I will move this over to our Single-Board Computers area as it is a better fit.

Thank you,

Jamie

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 ?
