  • Page 5 15 bit single ended or 16 bit fully differential - 1,024 increments per mv. The ADC-8U15HG may be set to accept (4) fully differential inputs in place of the (8) single ended inputs. The differential voltage input range is determined by the reference setting as shown on the previous page. The differential Option 11: .016 volt - allows a (0 to .016) volt input range or (-.016 to +.016) volts fully differential (= 0 to 16mv)
