Analog Devices Operational Amplifier : What is the voltage range that can be input to the digital control input DIGIN pin when the power supply voltage of the AD8557 is VDD=+2.5V and VSS=-2.5V?

Amplifier

The digital input voltage range of the AD8557 is VIL<0.2*VDD, VIH>0.8*VDD, and the absolute maximum rating of the input voltage is VSS−0.3V, VDD+0.3V. Therefore, when VDD=+2.5V, please use within the voltage range of -0.3V<VIL<+0.5V, +2.0V<VIH<+2.8V.
