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 (R
L
in the diagram
shown above) must be greater than 1 k
Ω.
