LDC1612EVM / Inductance data variation

Other Parts Discussed in Thread: LDC1612EVM, LDC1612

Hi,

My customer is evaluating LDC1612EVM and calculate inductance value from frequency count from log data, but then the data is varied per power-on.

[Question]

  • Should output data be exactly the same every time if all environment (temperature, voltage, distance to target… so on) is the same ideal?

[Condition]

  • DUT : LDC1612, all external components are default
  • GUI : LDC13xx16xx EVM GUI
  • Target : SUS304
  • Inductance value was calculated from Frequency Count value from log data
  • Test procedure
    • Power on and start 1st measurement for 30 min
    • Power off and wait 30 min
    • Power on again and start 2nd measurement for 30 min
    • Continue this cycle four times

Please also see attached data.
