The INA750x is a voltage output, current sense amplifier with an integrated shunt resistor of 800µΩ. The INA750x 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 ±35ppm/°C, and an optimized layout for the sensing resistor.
The INA750x is designed with enhanced PWM rejection circuitry to suppress disturbances from large (dv/dt) common-mode transients and enable real-time continuous current measurements in switcing systems. The continous measurements are critical for inline current measurements in a motor-drive application, and for solenoid valve control applications
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 VQFN package.
