9 Power Supply Recommendations

The LMH2110 is designed to operate from an input voltage supply range between 2.7 V to 5 V. This input voltage must be well regulated. Enable voltage levels lower than 400 mV below GND could lead to incorrect operation of the device. Also, the resistance of the input supply rail must be low enough to ensure correct operation of the device.
