TDC1000-TDC7200EVM: TDC1000-TDC7200EVM: Need details about each input parameters / boxes those appears in the software.

Part Number: TDC1000-TDC7200EVM

Hello,

I was reading the user manual to get more information about the input parameters / boxes those appears in the software but didn't find any such details. I want to know the meaning and what are those values so that I can change those if needed. So where can I find all those details? Also how to change the input voltage and frequency value in those parameters for excitation of transducers?

Thanks.

The EVM GUI has 2 Tabs TDC1000 & TDC7200 Tabs all the parameters in these tabs you will find them in the respective datasheet.
The EVM is designed to work with the steminc transducer that it ships with and the exitation voltage is based on that transducer, in case you want to use a different transducer, you can provide separate voltage to it as required.

Ok. I will go through those datasheets of TDC1000 & TDC7200 for details. How to provide separate voltage if I am using different sensors? Which parameter needs to be changed and how?
Thanks.

Prabhav,

If your using the TDC1000-TDC7200EVM it can at maximum provide a 5V to the transducer, in case you need to supply more than 5V for your transducer you could use our TDC1000-BSTEVM which has a booster circuit that can supply upto 30V.
Please note that the TDC1000 device cannot handle more than 5V and you will need to use the TDC1000-GASEVM & TDC1000-BSTEVM combine for the same.
Also note that the TDC1000-TDC7200EVM the RC circuit at the PGAIN LNA pins are centered to be used for resonant freq of 1MHz and you will ave to change to suit your transducers resonant frequency. However the 1MHz transducer should be apt for any measurement through liquids.
