The SGM8198 is a high-side, unipolar, current shunt monitor. Wide input common mode voltage range, high-speed, low quiescent current and tiny packaging enable SGM8198 to be used in a variety of applications.
Input common mode voltage can range from VCC to 26V for the SGM8198. Quiescent current is only 60μA, which permits connecting the power supply to either side of the current measurement shunt with minimal error.
The device converts a differential input voltage to a current output. This current is converted back to a voltage with an external load resistor that sets any gain from 1 to over 100. Although designed for current shunt measurement, the circuit invites creative applications in measurement and level shifting.
