6.3.5 Wide Supply Range

The INA187 operates with a wide supply range from 2.7V to 12V. While the input common-mode voltage range of the INA187 is independent of the supply voltage, the output voltage is bound by the supply voltage applied to the device. The output voltage can range from as low as 80mV to as high as 100mV below the supply voltage.
