How to calculate IDD of LDC0851EVM?

Other Parts Discussed in Thread: LDC0851EVM, LDC0851

Dear Technical Support Team,


I'd like to calculate IDD of LDC0851EVM because it is used on battery.


Datasheet shows that IDD   Idyn + Istatic + Isensor.

Each calculations are below.


Istatic = 0.77mA(typ) on datasheet Page.5.

Idyn =(24.262x10^-12) x fsensor + 1.5 x fsensor x Cboard.

Isensor = 1 / (17.1 x Lsensor x fsensor)


LDC0851EVM User guide shows below specification of LSENSE SENSOR and LREF SENSOR on Page.6.


ƒSENSOR (no target): 9.5 MHz

But I don't know Cboard and Lsensor on userguide.


Best Regards,
