产品概述
The INA138 and INA168 (INA1x8) are high-side, unipolar, current shunt monitors. Wideinput common-mode voltage range, low quiescent current, and tiny SOT-23 packaging enable use in avariety of applications. Input common-mode and power-supply voltages are independent and can range from 2.7 V to36 V for the INA138 and 2.7 V to 60 V for the INA168. Quiescent current is only 25 µA, whichpermits connecting the power supply to either side of the current measurement shunt with minimalerror. The device converts a differential input voltage to a current output. This current isconverted 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 inmeasurement and level shifting.
