Question
Can you confirm 2's Complement coding in Table 14 of AD5724 datasheet Rev. D?
Answer
The limits for a 2's Complement are (-2(n-1))…0…(+2(n-1)-1) à 2047…0…2048.
The Table 14 in the datasheet should indicate the values as follows for +/5V
Output:
+2 X REFIN X (2047/2048)
+2 X REFIN X (2046/2048)
+2 X REFIN X (2045/2048)
…
+2 X REFIN X (1/2048)
0
-2 X REFIN X (1/2048)
-2 X REFIN X (2/2048)
…
-2 X REFIN X (2046/2048)
-2 X REFIN X (2047/2048)
-2 X REFIN X (2048/2048)
