I have a question about figure23 of ADCMP572's datasheet.
There is a discripsion "GND = -1V" in the figure.
Could you please advise me the "GND = -1V" mean? (If that means is that GND pin (#13and#15) connects -1V, ADCMP572's output Level of "Low" is also -1V.)
There are some application where the input signal means at 0V and rails at +/-1V, and using figure 32 on the datasheet will accept this kind of signal.
Even with this input levels, the output of ADCMP572 are still CML hence it will still be in the range of what is written in the "DC OUTPUT CHARACTERISTIC" on page 3 of the datasheet, where the differential output level = 375mV close to VCCo.
thank you for your advice.
I misunderstood about the OUTPUT stage function.
I understand your advice.
