Tool/software: TI C/C++ Compiler
Hello everyone:
Here's a question about the out put data of the device. When I collect voltages data in the ±10V, the result supposed to be like this according to the reference book:
----------------------------------
LSB: 152uV
+Full-scale: 9.999848V -> 7FFF
Midscale: 0V -> 0000
One LSB below midscale: -0.000002 -> FFFF
-Full-scale: -10V -> 8000
----------------------------------
However, the real data goes like this：
----------------------------------
LSB: 152uV
+Full-scale: 9.999848V -> FFFF
Midscale: 0V -> 0000
One LSB below midscale: -0.000002 -> FFFF
-Full-scale: -10V -> 0000
----------------------------------
It's strange isn't it? Seems like the highest bit is not the symbolic bit or stuff.
Did I do sth wrong? Please help me .
Thank you so much.
Best whishes
