The Texas Instruments INA381A1QDGSRQ1 is an automotive-qualified current sense amplifier with an integrated overcurrent comparator. It is designed to measure voltage across a current-shunt resistor and detect overcurrent conditions.
This device supports a common-mode input voltage range from -0.2 V to 26 V, independent of the supply voltage. It offers high accuracy with a maximum offset voltage of 500 µV at 12 V common-mode and a maximum offset voltage drift of 1 µV/°C. The gain error is a maximum of 1% at 25°C, with a gain error drift of 20 ppm/°C.
The INA381A1-Q1 variant provides a voltage gain of 20 V/V. It operates from a single 2.7-V to 5.5-V supply and consumes a maximum of 350 µA. The device is specified for an operating temperature range of -40°C to +125°C.
Packaged in a 10-VSSOP, the INA381A1QDGSRQ1 is suitable for surface mounting. Its features make it ideal for applications such as ADAS domain controllers, body control modules, and automotive head units.
