Tool/software:
hi team,
my customer is testing LDC1612 and their inductance of the sensor is 3.6mH , the capacitance is 1nF.
they want to set the frequency as 80k . But after they set the register, the frequency stays un-change. do u have any advise?
Hello Zoey,
The frequency is determined by the LC tank circuit. For their LC values, the frequency should be 84kHz. The excel calculator tool below can be used to calculate the frequency.

The divider registers should be set based on the resonant frequency of the tank circuit. Section 8.2.4 of the datasheet details the procedure of setting these registers.
