Product Overview: INA250AIPWR by Texas Instruments

The INA250AIPWR is a precision power monitor from Texas Instruments, designed to provide high-accuracy current and power measurement capabilities to a wide range of applications. This integrated circuit simplifies the design of power management systems by combining a current-sensing amplifier and a precision shunt resistor in one compact package.

Key Features

• Integrated Shunt Resistor: The INA250AIPWR includes a precision-matched, temperature-compensated 2mΩ shunt resistor, which provides high-accuracy current sensing without the need for external components.
• Wide Common-Mode Range: Capable of monitoring shunt voltage across a wide common-mode range from 0 to +36V, this device is suitable for a variety of supply rails and systems.
• High Accuracy: With an accuracy of ±0.1% (max) over the temperature range of -40°C to +125°C, the INA250AIPWR ensures precise measurements for critical applications.
• Output Voltage Proportional to Current: The output of the INA250AIPWR is a voltage proportional to the current passing through the shunt resistor, which can be easily interfaced with analog-to-digital converters (ADCs) or other monitoring circuitry.
• Multiple Gain Options: Available in four gain options (20, 50, 100, and 200 V/V), this device can be selected to match the specific requirements of different applications.
