Product Details

The LTC6115 is a versatile combination of a high voltage, high side current sense amplifier and a voltage sense amplifier. Design flexibility is provided by the excellent device characteristics: ±500µV maximum offset voltage for current sense and maximum ±0.15% voltage sense total gain error.

The current sensing part of the LTC6115 monitors current by sensing the voltage across an external sense resistor. The sensed voltage is converted to an output current which can then be translated to a voltage by an external resistor, ROUT. Due to its fast response, it is a perfect choice for load current warning and shut-off protection control.

The LTC6115 also includes an internal 1MΩ resistor divider and a precision voltage amplifier for accurate voltage monitoring. The resistor attenuation of 40 enables sensing of up to 100V on the VIN pin, making it suitable for precision high voltage monitoring in telecommunications, industrial and automotive applications. The full-scale output voltage can be configured by external gain resistors to maximize use of the amplifier’s rail-to-rail output. The LTC6115 is available in a 12-lead MSOP package.
