Hi, may I extend this discussion about AD8495?
I try to use AD8495 to measure K type TC from 15 to 1100 deg.C.
The output of AD8495 is about 5.5V at 1100 deg.C.
I will supply 6V to +Vs pin of AD8495.
But for isolation consideration, I plan to connect the output of AD8495 to V/F AD7741.
I choose these two parts for low cost reason.
Unfortunatly, the input range of AD7741 is 2.5V.
For the buffer input of AD7741, I plan to use the resistors (20kohm and 10kohm) to devide the voltage.
I think it is not a good solution for the error increase in CJC.
Please give me some advice. Thank you.
