INA381A3IDSGR Description

Short technical summary and product information.

The Texas Instruments INA381A3IDSGR is a versatile current sense amplifier designed for precise current monitoring and overcurrent detection. It operates with a wide common-mode input range from -0.2V to 26V, making it suitable for various applications.

 

This device offers high accuracy with a gain error of ±1% at 25°C and an offset voltage drift of only 1 µV/°C. The integrated high-speed comparator includes hysteresis and can be configured in transparent or latched modes for flexible alert signaling. The INA381A3IDSGR is available in an 8-WSON (2x2) package, suitable for surface mounting.

 

Key electrical specifications include an offset voltage of 500 µV maximum at 12V common-mode and 150 µV maximum at 0V common-mode. The gain is set at 100 V/V for this specific variant. The operating temperature range is -40°C to 125°C.

 

This component is ideal for applications requiring accurate current measurement and protection, such as battery management systems, power supplies, and motor control.
