Analog current-sense amplifiers with integrated shunt resistor
Enable improved system accuracy, feedback control and protection while integrating the shunt resistor
Current-sense amplifiers with integrated shunt resistors provide calibration equivalent measurement accuracy and low temperature drift performance while ensuring an optimized Kelvin layout for the sense resistor. These devices also enable high-accuracy current measurements at common-mode voltages above supply.
