LTC6115 High Side Current & Voltage Sense Analog Devices LTC6115 High Side Current and Voltage Sense is a versatile combination of a high voltage, high side current sense amplifier and a voltage sense amplifier, providing design flexibility with excellent device characteristics. The LTC6115 features ±500µV maximum offset voltage for current sense and a maximum ±0.15% voltage sense total gain error. The LTC6115 monitors current by sensing the voltage across an external sense resistor. The sensed voltage is converted to an output current, then is available to be translated to a voltage by an external resistor, ROUT. The device is perfect for load current warning and shut-off protection control due to its fast response time.
