Enhanced PWM rejection (80dB) suppresses common-mode transients from inverter switching for motor drive current sensing. AEC-Q100 qualified for automotive applications.","working_principle":"The differential input voltage across the shunt resistor is amplified by the fixed 200 V\/V gain. The high-impedance inputs are protected for common-mode voltages from -4V to +80V. The internal reference pin sets the zero-current output level (typically mid-supply for bidirectional). Enhanced PWM rejection uses a proprietary sample-and-hold technique to suppress common-mode switching transients from PWM motor drives.","pin_description":"
