Introduction

AI Translation

The INA138 and INA168 (INA1x8) are high-side unipolar current shunt monitors. These devices combine a wide input common-mode voltage range with low quiescent current and are packaged in a small SOT-23 package, making them suitable for a wide range of applications. The input common-mode and supply voltages are independent of each other. The voltage range of the INA138 is from 2.7V to 36V, and that of the INA168 is from 2.7V to 60V. With a quiescent current of only 25μA, the supply can be connected to either side of the current-measuring shunt with very low error. The device can convert a differential input voltage to a current output. This current is then converted back to a voltage using an external load resistor, which can set the gain range from 1 to over 100. Although the circuit is designed for shunt measurements, it is also well-suited for measurements and level shifting in creative applications. Both the INA138 and INA168 are available in an SOT23-5 package and are specified for operation over a temperature range of -40°C to 125°C.
