More Information

The INA253-Q1 is an automotive, voltage-output, current sense amplifier with an integrated shunt resistor of 2 mΩ. The INA253-Q1 monitors bidirectional currents over a wide common-mode range from –4 V to +80 V, independent of the supply voltage. Three fixed gains are available: 100 mV/A, 200 mV/A, and 400 mV/A. The integration of the precision resistor with a zero-drift chopped amplifier provides calibration-equivalent measurement accuracy, ultra-low temperature-drift performance of 15 ppm/ °C, and an optimized Kelvin layout for the sensing resistor.
