TLA2024EVM-PDK: TLA2024 Accuracy Issue

Part Number: TLA2024EVM-PDK

Hi,

I am using TLA2024EVM-PDK evaluation board. But i am facing accuracy issue. I am observing maximum 17mV difference between measured value and the data received from I2C. below are the results,

Vsense(Measured)  I2C received Value vmeas-VBLE Error in %
0.295 0.291 0.004 1.355932
0.456 0.444 0.012 2.631579
0.616 0.6 0.016 2.597403
0.779 0.762 0.017 2.182285
0.941 0.924 0.017 1.806589
1.029 1.016 0.013 1.263362
1.228 1.23 -0.002 -0.16287

1.472 1.473 -0.001 -0.06793
1.517 1.518 -0.001 -0.06592

Our voltage range is from 0.290V to 2V. For this we are using FSR as +-2.048. Can you please guide on this how to reduce the error rate.

Thanks & Regards,

  • Hi Muralikrishna,

    Welcome to our e2e Forum!  Everyone is home for the holidays until Monday the 27th.  In the meantime, can you let us know how you have the TLV2024EVM-PDK setup?  What is your voltage source, what are your jumper settings, and what sort of meter are you using to measure Vin?
