INA381A1IDSGR Description

Short technical summary and product information.

The Texas Instruments INA381A1IDSGR is an analog current sense amplifier featuring an integrated over-current comparator. It supports a wide common-mode voltage range from -0.2V to 26V, making it suitable for various power management applications.

 

This device boasts high accuracy with a maximum gain error of 1% at 25°C and a low input offset voltage drift of 1 µV/°C. The amplifier offers selectable voltage gains of 20, 50, 100, or 200 V/V and a bandwidth of up to 350kHz, depending on the gain setting. The integrated open-drain comparator includes hysteresis and supports transparent and latching modes.

 

The INA381A1IDSGR is available in an 8-WSON (2x2 mm) package, designed for surface mounting. Its operating temperature range is -40°C to 125°C.

 

This current sense amplifier is ideal for applications requiring precise current monitoring and over-current detection.
