The INA751x-Q1 is a voltage output, current sense amplifier with an integrated shunt resistor of 800µΩ. The INA751x-Q1 is designed to monitor bidirectional current over a common-mode range of –4V to +110V, independent of the supply voltage. Adjustable gain option assists in optimizing the system dynamic range. The integration of the Kelvin connected shunt resistor with a zero-drift chopped amplifier provides calibration equivalent measurement accuracy, ultra-low temperature drift performance of ±40ppm/°C, and an optimized layout for the sensing resistor. This device operates from a single 2.7V to 5.5V power supply, drawing a maximum of 4.25mA of supply current. All versions are specified over the extended operating temperature range (–40°C to +125°C), and are available in a 14-pin wettable flank VQFN package.
