Description
The TSC1031 measures a small differential voltage on a high-side shunt resistor and translates it into a ground-referenced output voltage. The TSC1031’s dedicated schematic eases the implementation of EMI filtering in harsh environments. The gain is adjustable to 50 V/V or 100 V/V by a selection pin.
Wide input common-mode voltage range, low quiescent current, and tiny TSSOP8 packaging enable use in a wide variety of applications.
