ZHCSJ78 December 2018 INA240-SEP
PRODUCTION DATA.
The INA240-SEP makes accurate measurements beyond the connected power-supply voltage (VS) because the inputs (IN+ and IN–) operate anywhere between –4 V and 80 V independent of VS. For example, the VS power supply equals 5 V and the common-mode voltage of the measured shunt can be as high as 80 V.
Although the common-mode voltage of the input can be beyond the supply voltage, the output voltage range of the INA240-SEP series is constrained to the supply voltage.
