INA240 Zero-Drift Current Sense Amplifiers
Texas Instruments INA240 Zero-Drift Current Sense Amplifiers are a voltage-output, current-sense amplifier 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 levels of suppression for large common-mode transients (ΔV/Δt) in systems that use pulse width modulation (PWM) signals. This feature allows for accurate current measurements without large transients and associated recovery ripple on the output voltage.
