This device is housed in a SOIC-8 package and operates across a 0\u00b0C ~ +70\u00b0C. It supports a supply voltage range of 2V ~ 36V (\u5355\u7535\u6e90) \u6216 \u00b11V ~ \u00b118V (\u53cc\u7535\u6e90). The device features 2 channel(s). The component meets industry standards for reliability and is suitable for demanding applications.","working_principle":"The device amplifies the differential voltage between its inverting and non-inverting inputs. The high open-loop gain enables precise signal conditioning with external feedback networks setting the closed-loop gain. Rail-to-rail input\/output capability ensures maximum dynamic range in single-supply applications.","pin_description":"
