ABSTRACT:
An adaptive range circuit (10) suitable for use with an analog to digital convertor (11) having operating range control inputs. The invention includes a peak detection unit (12) that can include a positive peak detector (13) and a negative peak detector (14) that provide signals representative of positive and negative peaks for the incoming analog signal to be digitized. These representative signals can be utilized to control the operating range of the A/D convertor (11).
