3 Configuration and calculation of SIGMA-DELTA filter module based on integration of AMC1305M25 and F28377S

SINC filter is flexible to configure and the output result is closely related to the oversampling rate and SINC filter order. This chapter describes how to complete the voltage sampling function using the F28377SSDFM module and the AMC1305M25. The input analog signal amplitude for AMC1305M25 is acquired by reading F28377S SDFM register.
