10.8 DAC transfer function
The full scale output current for each DAC is the sum of the two complementary current
outputs:
(3)
The output current depends on the digital input data:
(4)
(5)
The setting applied to register COMMON bit DF (register 00h[2]; see
Table 17
) defines
whether the DAC1408D650 operates with a binary input or a two’s complement input.
Table 12
shows the output current as a function of the input data, when I
O(fs)
= 20 mA.
