The is a versatile high voltage high side Dual Current Sense Amplifier for use with battery monitoring and remote sensing. The two internal amplifiers are independent except that they share the same V- terminal. Design flexibility is provided by the excellent device characteristics of 450µV maximum offset and only 275µA of current consumption typical at 12V for each amplifier. The LTC6103 operates on supplies from 4 to 60V. The LTC6103 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 fast response makes the LTC6103 the perfect choice for load current warnings and shutoff protection control.
