  • NI-9266
  • NI-9265

Issue Details

Can you both source and sink current from a NI-9265 or NI-9266?


The NI-9265 and NI-9266 can only source current from their Analog Output Pins. The NI-9265 can not control both magnitude and direction of current. 

Additional Information

The NI-9266 Datasheet contains the figure below. This figure shows that the current flows from the Vsup pin connected to the external power supply to the AO pin. This is the same for the NI-9265.
Additionally, the current range of the NI-9266 and the NI-9265 is from 0 mA to 20 mA. With these two pieces of information, we know that the NI-9266 and the NI-9265 can only source current, it cannot sink current from its AO pins.
