  • The TSC888 measures a small differential voltage on a high-side shunt resistor and translates it into a ground-referenced output voltage. The gain is internally fixed.

    Wide input common-mode voltage range, low quiescent current, and tiny SOT23-5 packaging make the TSC888 ideal for use in a wide variety of applications.
    Input common-mode and power supply voltages are independent. Common-mode voltage can range from 2.8 V to 24 V in operating conditions.
    Current consumption lower than 1 mA and wide supply voltage range allow to connect the power supply to either side of the current measurement shunt with minimal error.

    Key Features

    • Buffered output
    • Independent supply and input common-mode voltages
    • Wide supply voltage range: 4 to 24 V
    • Wide common-mode operating range: 2.8 V to 24 V
    • Internally fixed gain: 20 V/V, 50 V/V or 100 V/V
    • Low current consumption: ICC max = 1 mA
