Linear Technology’s current sense amplifier, the LT6100, is a complete high-side current sense solution. Simply connect a high side shunt to the inputs; the LT6100 extracts and then amplifies the differential signal and provides a ground-referenced output signal. Using internal resistors, the amplifier can be configured for one of six gain settings with a gain accuracy of 0.5%. A buffered output allows the part to be directly loaded by other circuitry. The LT6100 has robust differential inputs with a low 300 uV offset and can accept fully differential voltages up to the supply. The LT6100 uses Over-The-Top® architecture with a separate voltage supply that operates from 2.7 V to 36 V and draws 60 uA. When powered down, the sense pins are high impedance.
