Our space-qualified products follow a standard naming configuration: partnameS. (e.g. AD8561 space-qualified equivalent is AD8561S)
We do not have ADA8561 in our portfolio. Did you mean AD8561? As mentioned, the space-qualified equivalent…
How to measure he CMRR, offset current, bias current and offset voltage of AD8561 Comparator? Can you elaborate on the test circuits and test methods to test these parameters.?
The Vout is getting saturated on trying to determine the input offset voltage of AD8561 through below servo circuit.
Please help to confirm whether this approach is good to proceed and also please provide your suggestion.
Can you clarify whether your question is on the AD8561 (as in the title) or AD584?
With regard to the AD584, based on the datasheet, yes, you do need 2.5V headroom from output to supply.
I need to SI simulations in HSpice with the AD8561 and download the spice.cir. After changed the spice.cir to the spice.sp used in HPspice , errors happened, as figure.
however, this spice.cir can work in PSpice Soffware normally, as figure.
I'm looking at the LATCH pin in AD8561.
It seems like LATCH logic threshold values are strange.
For example, LATCH pin Logic "0" (TYP) should be less than (MAX).
But, Datasheet shows (TYP)=1.6V, (Max) = 0.8V
Could anyone explain…
