voltage-mode operation
The current-multiplying DAC in these devices can be operated 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. An example of a current-multiplying DAC operating in voltage mode is shown in Figure 6. The
relationship between the fixed input voltage and the analog output voltage is given by the following equation:
Analog output voltage = fixed input voltage (D/256)
where D = the digital input. In voltage-mode operation, these devices meet the following specification:
