The LT6015/LT6016/LT6017 are single/dual/quad rail-to-rail input operational amplifiers with input offset voltage trimmed to less than 50μV. These amplifiers operate on single and split supplies with a total voltage of 3V to 50V and draw only 315μA per amplifier. They are reverse battery protected, drawing very little current for reverse supplies up to 50V.The Over-The-Top®input stage of the LT6015/LT6016/LT6017 is designed to provide added protection in tough environments. The input common mode range extends from V–to V+and beyond: these amplifiers operate with inputs up to 76V above V–independent of V+. Internal resistors protect the inputs against transient faults up to 25V below the negative supply. The LT6015/LT6016/LT6017 can drive loads up to 25mA and are unity-gain stable with capacitive loads as large as 200pF. Optional external compensation can be added to extend the capacitive drive capability beyond 200pF.The LT6015 is offered in a 5-lead SOT package. The LT6016 dual op amp is available in an 8-lead MSOP package. The LT6017 is offered in a 22-pin leadless DFN package.ApplicationsHigh Side or Low Side Current SensingBattery/Power Supply Monitoring4mA to 20mA TransmittersHigh Voltage Data AcquisitionBattery/Portable Instrumentation
