ADSP-TS203S
OUTPUT DRIVE CURRENTS
Figure 24 through Figure 31 show typical I–V characteristics for
the output drivers of the ADSP-TS203S processor. The curves in
these diagrams represent the current drive capability of the out-
put drivers as a function of output voltage over the range of
drive strengths. For complete output driver characteristics, refer
to the processor’s IBIS models, available on the Analog Devices
website (www.analog.com).
