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.

Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
The ADALM-SR1 (Analog Devices Active Learning Module, Switching Regulator) board is a companion module for several switching regulator exercises covering buck and boost regulators:
- Boost and Buck converter elements and open-loop operation
- Buck Converters: closed loop operation
- Boost Converters: closed loop operation
The circuits required for these exercises exceed the complexity that can be constructed on a breadboard, so the ADALM-SR1 was designed as a flexible platform for experimenting with power electronics. Onboard current sense amplifiers, adjustable electronic load, and feedback signal injection circuitry eliminate the need for expensive equipment — the only additional equipment required is:
- 5V USB wall adapter
- Basic adjustable power supply for input power (0-12V, 2A)
- ADALM2000 or basic oscilloscope (2 channels with trigger, >10MHz bandwidth)
Features & Benefits
- Companion module for Active Learning labs on buck and boost power converters
- Illustrates important concepts related to buck and boost converters:
- Continuous vs. Discontinuous Conduction Modes
- Open loop operation
- Voltage mode control
- Current mode control
- Independently adjustable parameters: frequency, duty cycle, voltage/current mode
- Onboard current sense amplifiers and adjustable load minimize equipment requirements.
