... LTC6102/LTC6102HV APPLICATIONS INFORMATION The LTC6102 high side current sense amplifi er (Figure 1) provides accurate monitoring of current through a user- selected sense resistor. The sense voltage is amplifi user-selected gain and level shifted from the positive power supply to a ground-referred output. The output signal is analog and may be used processed with an output fi ...
