The INA138-Q1 and INA168-Q1 are high-side, unipolar, current shunt monitors. Wide input common-mode voltage range, low quiescent current, and tiny TSSOP and SOT23 packaging enable uses in a variety of applications.
Input common-mode and power-supply voltages are independent and can range from 2.7 V to 36 V for the INA138-Q1 and 2.7 V to 60 V for the INA168-Q1. Quiescent current is only 25 μA, 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.
Both the INA138-Q1 and INA168-Q1 are available in TSSOP−8 and SOT23−5 and are specified for the –40°C to 125°C temperature range.
