AEC-Q100 Grade 1 qualified for -40 to 125\u00b0C. Fixed gain of 1 with 0.05% max nonlinearity. Fail-safe output drives to mid-supply on fault.","working_principle":"Uses capacitive isolation technology. High-side delta-sigma modulator digitizes differential input into 1-bit stream, coupled across capacitive barrier to low-side digital filter for analog output reconstruction. Fail-safe monitors VDD1; when undervoltage, output transitions to VDD2\/2. Reinforced barrier certified to 7000VPEAK per IEC 62368-1.","pin_description":"
