♠ INA1x9 High-Side Measurement Current Shunt Monitor
The INA139 and INA169 are high-side, unipolar, current shunt monitors. Wide input common-mode voltage range, high-speed, 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 40 V for the INA139 and 2.7 V to 60 V for the INA169. Quiescent current is only 60 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 INA139 and INA169 are available in 5-pin SOT-23 packages. The INA139 device is specified for the –40°C to +125°C temperature range, and the INA169 is specified from –40°C to +85°C.
