About Evaluation board AD5933

Former Member
Former Member over 11 years ago

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 ?
