Voltage output, high/low side measurement, bidirectional, zero drift series 'INA240'
The INA240 is a current sense amplifier with voltage output that can detect the voltage drop across a shunt resistor over a wide common-mode voltage range of -4V to 80V, independent of the supply voltage, thanks to its enhanced PWM rejection feature. Due to the negative common-mode voltage, the device can operate at potentials lower than ground and can accommodate the flyback period of standard solenoid applications. With enhanced PWM rejection, it suppresses large common-mode transient voltages (ΔV/Δt) at high levels in systems using pulse width modulation (PWM) signals. This feature allows for accurate current measurement without large transient voltages or associated output voltage recovery ripple. 【Features】 ■ Enhanced PWM rejection ■ Excellent CMRR ■ Wide common-mode voltage range: -4V to 80V ■ Accuracy ・ Gain error: 0.20% (maximum) ・ Gain drift: 2.5 ppm/°C (maximum) *For more details, please contact us.
