Standardized analog input front end device and method

摘要

Analog input front end includes setting possible profit stage and the analog digital transmitter. Setting possible profit stage receives the analog input signal like the differential analog input signal, in order to output the gain control analog input signal inside the voltage range of specification with maximum and minimum, offers profit value to the analog input signal. The analog digital transmitter receives the gain control analog input signal, in order to output the digital signal which displays the analog input signal, executes analog digital conversion in the gain control analog input signal.
