Product data sheet
10.10.1 Regulation
10.10 Full-scale current
10.9 DAC transfer function
Table 34.
The full-scale output current for each DAC is the sum of the two complementary current
outputs:
The output current depends on the digital input data:
The setting applied to CODING (register 00h[2]; see
defines whether the DAC1405D650 operates with a binary input or a two’s complement
input.
Table 35 “DAC transfer function”
when I
Table 35.
The DAC1405D650 reference circuitry integrates an internal bandgap reference voltage
which delivers a 1.25 V reference to the GAPOUT pin. It is recommended to decouple pin
GAPOUT using a 100 nF capacitor.
