I have a question about ADUM2484E differential output voltage.
If use VDD2=3.3V , TA=25℃, why is an area so wide 1.5Vto 3.6V?
If you have differential output voltage Histogram , can i have it ? please teach me ...
Best regards ,
As shown in the Typical Performance curves, the typical differential output voltage with 54 Ohm load, is 2.1V.
The differential output voltage will vary noticeably with the wide Vdd2 range of 3V to 3.6V, and of course it's necessary to allow for variation over temperature and production process.
The part is designed to ensure it meets the RS-485 standard minimum Vod of 1.5V, while 3.6V can be guaranteed as a maximum because that's the maximum voltage for Vdd2. In practice, the Vod will not be as large as 3.6V.
Hi Conal ,
Thank you very much for your supports.
There is a question additionally.
If in this case VDD1=VDD2=3.2-3.4V,Max temperature 65℃,
Driver differential output voltage(1.5V to 3.6V), the spec of which degree will it be?
and Receiver differential input threshold (-200mV to -30mV), the spec of which degree will it be?
If you have a data , please teach me ...
I think my before question is difficult , so change it . Im sorry.
If in this case only VDD1=VDD2=3.2-3.4V, temperature conditions aren't considered.
I think nearly differential output voltage with 54 Ohm load, is 2.1V..
So if you have something datas, please teach me ...
Retrieving data ...
