INA381A1IDSGT Description

Short technical summary and product information.

The INA381A1IDSGT from Texas Instruments is a versatile current sense amplifier designed for high-side or low-side current monitoring. It operates with a wide common-mode input range of -0.2V to +26V, making it suitable for various applications.

 

This device offers high accuracy with a maximum gain error of 1% at 25°C and a low offset voltage drift of 1 µV/°C. The integrated high-speed comparator with 50mV hysteresis allows for efficient overcurrent detection by comparing the shunt voltage to a user-defined threshold.

 

The INA381A1IDSGT is available in an 8-WSON package, suitable for surface mount applications. Its operating temperature range is -40°C to 125°C, ensuring reliable performance in demanding environments. The amplifier gain for this specific model is 20 V/V.

 

This current sense amplifier is ideal for applications requiring precise current monitoring and overcurrent protection, such as battery management systems, power supplies, and motor control.
