PGA970: PGA970 BPF/LPF Coeffiecients Calculation

Torsten Aurich

Part Number: PGA970

Dear TI-Team,

currently i'm checking the PGA970-EVM with the GUI for a new application.
In this application we want to use an LVDT-Sensor with the PGA970.

Can you tell me how do i calculate the coefficients for the BPF and the LPF?

Hi Torsten,

We have a proprietary calculator that is unavailable for distribution. If you know the frequencies you would like to use please post them, and I can respond with the coefficient values. For example here are the values for some frequencies for the low pass filter:
