Description
General part information
INA253-Q1 Series
The INA253-Q1 is an automotive, voltage-output, current sense amplifier with an integrated shunt resistor of 2 mΩ. The INA253-Q1 monitors 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-Q1 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 operating temperature range of –40 °C to +125 °C, and are available in a 20-pin TSSOP package.
