TABLE II. Digital Input and Analog Output Relationships.  
If the output cannot be sensed at Common or the system  
ground point as mentioned above, the differential output  
circuit shown in Figure 8 is recommended. In this circuit the  
output voltage is sensed at the load common and not at the  
D/A converter common as in the previous circuits. The value  
of R6 and R7 must be adjusted for maximum common-mode  
rejection at RL. Note that if R3 is negligible, the circuit of  
Figure 8 can be reduced to the one shown in Figure 7. Again  
the effect of R4 is negligible.  
The D/A converter and the wiring to its connectors should be  
located to provide optimum isolation from sources of RFI  
and EMI. The key concept in elimination of RF radiation or  
pickup is loop area; therefore, signal leads and their return  
conductors should be kept close together. This reduces the  
external magnetic field along with any radiation. Also, if a  
single lead and its return conductor are wired close together,  
they present a small flux-capture cross section for any  
external field. This reduces radiation pickup in the circuit.

RB should be equal to the output impedance at the current output  
to compensate for the bias current drift of A1. Use standard 10%,  
1/4W carbon composition or equivalent resistors.
