Texas Instruments INA206AID High-Side Measurement Current Shunt Monitor

The INA206AID from Texas Instruments is a precision current shunt monitor, designed to measure voltage drops across shunts at common-mode voltages from -16V to +80V, independent of the supply voltage. This high-side current monitor is particularly suitable for a wide range of applications, including power management, battery charging, and automotive systems, where precise current measurement is crucial.

This device operates with a single +3V to +5.5V power supply and draws a maximum of 900 μA of supply current. The INA206AID features a voltage output that makes it easy to interface with any microcontroller or analog-to-digital converter (ADC). The output is directly proportional to the measured current, and the proportionality factor (gain) can be selected among three fixed values (50V/V, 100V/V, and 200V/V) depending on the model.

The INA206AID offers excellent accuracy with a maximum input offset voltage of ±500 μV, which allows precise current measurement even at very low shunt voltage drops. Its high input common-mode voltage range and bandwidth make it perfect for stepping into high voltage systems safely without the need for complex level shifting or isolation techniques.

The device is available in an 8-pin SOIC package, ensuring easy integration into your circuit designs. It is also specified over the extended operating temperature range of -40°C to +125°C, making it suitable for use in harsh environments.

Key features of the INA206AID include:

• Wide common-mode voltage range: -16V to +80V
• High accuracy with low offset voltage
• Three selectable gains: 50V/V, 100V/V, 200V/V
• Low supply current: 900 μA (maximum)
• Wide supply voltage range: +3V to +5.5V
• Extended operating temperature range: -40°C to +125°C
• Industry-standard 8-pin SOIC package

Whether you are designing power supply systems, battery monitors, or any other application requiring precise current measurement, the INA206AID by Texas Instruments is an excellent choice for high-side current sensing.
