OUTPUT DRIVE CURRENTS
Figure 26
the output drivers of the ADSP-TS202S 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 DSP’s IBIS models, available on the Analog Devices web-
site (www.analog.com).
