The INA253 is designed to monitor 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, ultralow temperature drift performance of 15 ppm/°C, and an optimized Kelvin layout for the sensing resistor.
The INA253 is designed with enhanced PWM rejection circuitry to suppress large (dv/dt) signals that enable real-time continuous current measurements.
The 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.
7-V to 5.
5-V power supply, drawing a maximum of 3 mA of supply current.
