APPLICATION INFORMATION
voltage-mode operation
It is possible to operate the current multiplying D/A converter of these devices in a voltage mode. In the voltage
mode, a fixed voltage is placed on the current output terminal. The analog output voltage is then available at
the reference voltage terminal. Figure 11 is an example of a current multiplying D/A that operates in the voltage
mode.

Figure 11. Voltage-Mode Operation
The following equation shows the relationship between the fixed input voltage and the analog output voltage:
VO = VI (D/256)
Where:
VO = analog output voltage
VI = fixed input voltage (must not be forced below 0V.)
D = digital input code converted to decimal
In voltage-mode operation, these devices meet the following specification:
