Other Parts Discussed in Thread: LDC2114
The LDC2114 can provide a 12-bit (2's complement) measurement, so I would like to know what the relationship between the actual frequency and this relative value data is.
If the power is turned on with the target placed at a certain position from the coil, the measured value at that position will be zero by the base tracking algorithm, but the relative value at this time, the maximum value (0x7ff) and the Min value of the measurement range How does (0x800) relate to the frequency at zero value?
Supplement as it is not easy to understand.
When the frequency at the target position d = 0.5 ° is 3 MHz, how many frequencies correspond to the Max value and Min value in that state?
Although there are relative values, are there any relations between the frequency at the center value (0x000) and the frequencies at Max (0x7ff) and Min (0x800)?
Is it written in the data sheet of LDC2114 such as data sheet?
I think that the relative values of Max and MIn are determined based on the initial frequency (center frequency).
I apologize for being difficult to understand because I am not good at English
