Automotive current-sensing amplifier family with integrated internal shunt resistor

Texas Instruments’ automotive qualified INA250-Q1 is a voltage-output, current-sensing amplifier family that integrates an internal precision shunt resistor to enable high-accuracy current measurements at common-mode voltages that may vary from 0V to 36V, independent of the supply voltage. The family is available in four output voltage scales: 200mV/A, 500mV/A, 800mV/A, and 2V/A. This device is fully tested and specified for continuous currents up to 10 amps at the maximum temperature of +125C. The device operates from a single 2.7V to 36V supply and draws a maximum of 300µA of supply current. All device gain versions are specified over the extended operating temperature range of –40C to +125C, and are available in a TSSOP-16 package.
