INA138NA/3KG4 Description
The INA138 and INA168 (INA1x8) are high-side, unipolar, current shunt
monitors. Wide input commonmode voltage range, low quiescent current, and tiny
SOT-23 packaging enable use 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 and 2.7 V to 60 V for the INA168. 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 and INA168 are available in SOT23-5 and are specified for the
–40°C to 125°C temperature range.
