ABSTRACT:
Systems and apparatus are provided for interfacing a digital controller with an analog input means. The system comprises a digital controller with the input of the digital controller coupled to the output of the analog-to-digital converter. The system further comprises a digital-to-analog converter coupled to an analog interface circuit. The analog interface circuit comprises a reconfigurable RC network switchably coupled to a first amplifier or to a second amplifier. The analog interface circuit further comprises a third amplifier having an input being coupled to an output of the second amplifier and the output of the third amplifier being coupled to the one or more input signal paths to the first amplifier.
