The LT6013 and LT6014 op amps combine low noise and high precision input performance with low power consumption and rail-to-rail output swing. The amplifiers are stable in a gain of 5 or more and feature greatly improved CMRR and PSRR versus frequency compared to other precision op amps.Input offset voltage is factory-trimmed to less than 35µV. The low drift and excellent long-term stability ensure a high accuracy over temperature and time. The 250pA maximum input bias current and 120dB minimum voltage gain further maintain this precision over operating conditions.The LT6013 and LT6014 operate from any supply voltage from 2.7V to 36V and draw only 145µA of supply current per amplifier on a 5V supply. The output swings to within 40mV of either supply rail, making the amplifiers very useful for low voltage single supply operation.The amplifiers are fully specified at 5V and ±15V supplies and from -40°C to 85°C. The single LT6013 and dual LT6014 are both available in SO-8 and space saving 3mm × 3mm DFN packages. For unity gain stable versions, refer to the LT6010 and LT6011 data sheets.ApplicationsThermocouple AmplifiersPrecision Photodiode AmplifiersInstrumentation AmplifiersBattery-Powered Precision SystemsLow-Voltage Precision SystemsMicro-Power Sensor Interface

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
