MAX1434
Output Data Format (
T/B) Transfer Functions
The MAX1434 output data format is either offset binary
or two’s complement, depending on the logic-input T/B.
With T/B low, the output data format is two’s comple-
ment. With T/B high, the output data format is offset
binary. The following equations, Table 2, and Figures 6
and 7 define the relationship between the digital output
and the analog input. For two’s complement (T/B = 0):
and for offset binary (T/B = 1):
where CODE10 is the decimal equivalent of the digital
output code as shown in Table 2.
Keep the capacitive load on the MAX1434 digital out-
puts as low as possible.
