Hi Genny,
i am using the excel calculator very often but have never seen such an issue.
Can you please try to download the sheet again from:
https://www.ti.com/lit/zip/snvc181
delete the old version and check with the new file again.
Best regards,

Part Number: XTR111 The xtr111 is not working as intended. But When i reduce the supply voltage below 11.53 it gives a linear 4 - 20mA with my pwm input. But as soldered the part by hand, we cannot ensure the bottom thermal pad is connected to ground…
Part Number: TPS50601A-SP Tool/software: WEBENCH® Design Tools Could you please update the model to reflect that there is no min off time spec? See E2E thread

Part Number: VOLT-DIVIDER-CALC It is hard to believe that a design aid as poor as "VOLT-DIVIDER-CALC" should exist on TI's otherwise excellent web site.

Hi Sid,
No, the path cost changes. Sometimes the path cost value is usual but incorrect, for example, 3, 4, or 6, and at other times, the value is extremely high, above 100 or 200. I'm sharing with you a log from one device that we generated during our…
Mehmet,
Thanks for the details and answers to the questions.
I would suggest that you calibrate your sensor board including the XTR. That is, apply your loop supply to power the entire system and calibrate the output current. I am not in the lab today…
Hello,
Yes, you can parallel the TPS7A4700. We have released new resources last year detailing how to do this and an example for this LDO is listed in the first link below. You will want to use the digital voltage control pins, also known as the ANYOUT…
Hi,
From the settings described above, IDAC is still turned off.
The IDAC source needs to be turned on, otherwise there is no excitation source to bias the reference resistor and to generate a voltage across the RTD to be measured.
We have some useful…

Hi all, first time here.
I have been using a Nooelec USB RTL-based SDR ( NESDR SMArTee XTR ) with a Raspberry Pi (Zero 2 W) to capture wMBus readings off my Sharky 775 heat meter. This works perfectly…
