Voltage (DAC) Output
The 34907A module has two analog outputs capable of outputting
calibrated voltages between ±12 volts with 16 bits of resolution. Each DAC
(Digital-to-Analog Converter) channel can be used as a programmable
voltage source for analog input to other devices.
•You can set the output voltage to any value between +12 Vdc and
-12 Vdc, in 1 mV steps. Each DAC is earth referenced, it cannot float.
•Each DAC channel is capable of supplying 10 mA maximum current.
Note: You must limit the output current to 40 mA total for all three
slots (six DAC channels).
•To maintain the rated output accuracy, the load (RL in the diagram
shown above) must be greater than 1 kΩ.
