Product Summary

The INA169NA/250 is a high-side, unipolar, current shunt monitor. Wide input common-mode voltage range, high-speed, low quiescent current, and tiny SOT23 packaging enable use in a variety of applications. Input common-mode and power-supply voltages are independent and can range from 2.7V to 60V for the INA169NA/250. Quiescent current is only 60μA, which permits connecting the power supply to either side of the current measurement shunt with minimal error. The INA169NA/250 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. The INA169NA/250 is available in SOT23-5 packages and is specified for the –40℃ to +85℃ industrial temperature range.
