INA240A1QDRQ1, Current Sense Amplifiers AEC-Q100, -4 to 80V, bi-directional, ultra-precise current sense amplifier w/ enhanced pwm rejection
Semiconductors\Integrated Circuits - ICs\Amplifier ICs\Current Sense AmplifiersINA240/INA240-Q1 Current Sense Amplifiers Texas Instruments INA240/INA240-Q1 Zero-Drift Current Sense Amplifiers are voltage-output, current-sense amplifiers with enhanced PWM rejection. These amplifiers can sense drops across shunt resistors over a wide common-mode voltage range from –4V to 80V, independent of the supply voltage. The negative common-mode voltage allows the device to operate below ground, accommodating the flyback period of typical solenoid applications. Enhanced PWM rejection provides high suppression levels for large common-mode transients (ΔV/Δt) in systems that use pulse width modulation (PWM) signals. This feature allows accurate current measurements without large transients and associated recovery ripple on the output voltage. The Texas Instruments INA240-Q1 devices are AEC-Q100 qualified for automotive applications.
