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.
The input common-mode and power supply
voltages are independent. The common-mode
voltage can range from 2.9 to 70 V in the single-
supply configuration or be offset by an adjustable
voltage supplied on the Vcc- pin in the dual-
supply configuration.
With a current consumption lower than 360 μA
and a virtually null input leakage current in
standby mode, the power consumption in the
applications is minimized.
