The INA138NA from Texas Instruments is a high-side, unipolar current shunt monitor. It features a wide input common-mode voltage range independent of the supply voltage, spanning from 2.7 V to 36 V. This device is designed for efficient current measurement with a low quiescent current of only 25 μA typical, minimizing error when the power supply is connected to either side of the current measurement shunt.
The INA138NA converts a differential input voltage across a shunt resistor into a current output, which is then converted back to a voltage using an external load resistor. It offers a bandwidth of 800 kHz and operates reliably across a wide temperature range of -40°C to +125°C. The amplifier is housed in a compact 5-pin SOT-23 package, making it suitable for space-constrained applications.
This current sense amplifier is ideal for applications requiring precise monitoring of current flow. Its independent supply and input common-mode voltages, coupled with a single resistor gain set, provide design flexibility. The device is suitable for various power management and battery monitoring systems where accurate current sensing is critical.
