Preliminary data sheet
10.20 Output configuration
Table 19 shows the output current as a function of the auxiliary DACs data DATAA and
DATAB in Equation 13 to Equation 16.
Table 19.
The DAC1617D1G0 supports various output configurations.
The system application must check that for IOUTA/IOUTB output, the output compliance
range (V
respected to define other configurations.
Similarly, the system application must check that the output compliance range (V
specification point is respected for AUXA/AUXB DAC (if used).
The common-mode voltage (V
resistor(s) connected to these pins and the IOUT DC sink currents on these pins.
Equation 17 defines the DC sink output current is:
Where:
The common-mode voltage (V
resistor(s) connected to these pins and the AUX DC source currents.
Equation 18 defines these AUX DC source currents:
Where:
The output compliance range (V
connected to the DAC:
