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 |
1.385 | 1.386 | -0.001 | -0.0722 |
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,
