Question:  In your specifications, it states that the analog current output =  +/- 5mA minimum  (10V / 2KOhms).  Can you briefly explain?

 

Answer:  I have an application where I want to use one of the analog outputs to set 0 or 5  V to switch another circuit on and off. The other circuit input is Active Low (0 V), and internally pulled up to 5 V through a 10K resistor.  Is the 0.5 mA sink a safe value for the analog output pin?  The output amplifiers will supply +/-5 mA.  Typically it is 10V / 2K = 5mA but anything lower than the 10 volts will also drive the 5mA.  0.5mA is a safe value in all conditions.  Updated:  08/09/01.
