The INA253 is a voltage-output, current sense amplifier with an integrated shunt resistor of 2 mΩ. 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, ultra-low 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 in-line 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. All gain versions are specified over the extended operating temperature range (–40°C to +125°C), and are available in a 20-pin TSSOP package.
