Semiconductors\Amplifier ICs\Current Sense AmplifiersINA253/INA253-Q1 Current-Shunt MonitorTexas Instruments INA253/INA253-Q1 Current-Shunt Monitor is a voltage-output, current sense amplifier with an integrated shunt resistor of 2mΩ. The INA253/INA253-Q1 is designed to monitor bidirectional currents over a wide common-mode range from –4V to +80V, independent of the supply voltage. Three fixed gains are available: 100mV/A, 200mV/A, and 400mV/A. Integrating the precision resistor with a zero-drift chopped amplifier provides calibration equivalent measurement accuracy. This integration also offers ultra-low temperature drift performance of 15 ppm/°C and an optimized Kelvin layout for the sensing resistor.
