LTC6103HMS8#PBF

A versatile, high voltage, high side, dual current sense amplifier. The two internal amplifiers are independent except that they share the same V⁻ terminal. Design flexibility is provided by the excellent device characteristics: 450μV maximum offset, and only 275μA of current consumption (typical at 12V) for each amplifier. It operates on supplies from 4V to 60V. It monitors current via the voltage across an external sense resistor (shunt resistor). Internal circuitry converts input voltage to output current, allowing for a small sense signal on a high common mode voltage to be translated into a ground referenced signal. Low DC offset allows the use of a small shunt resistor and large gain - setting resistors. As a result, power loss in the shunt is minimal. The wide operating supply range and high accuracy make it ideal for an extensive variety of applications from automotive to industrial and power management. The fast response makes it the perfect choice for load current warnings and shutoff protection control. With very low supply current, it is suitable for power sensitive applications. It is available in an 8 - lead MSOP package.
