Question
Could you please give me some information about Input Common-Mode Voltage Range (Vcm)Min/typ/max , Logic 1 output voltage (Voh) for AD8561 forVcc=lower then 5.0V but more then 3.0V (something around 4 -4.3V are now expected)?
Answer
Unfortunately the AD8561 was not characterized on the 4.5V supply so we don’t have plots in that condition.
The input common mode voltage range is dependent on the supply itself. For a 4.5V single supply, the input common range could only be up to 4.5V.Forthe min/max logic 1, it is dependent on the supply and the ILOAD . If we look at the spec table at the 5.0V single supply, we can approximateVOH(min_4.5V)=3.0V @ IOH=-50uA.
