『INA240』

『INA240』

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.
