Output Drive Currents
Figure 14
the output drivers of the ADSP-TS101S. The curves in these
diagrams represent the current drive capability of the output
drivers as a function of output voltage over the range of drive
strengths. For complete output driver characteristics, refer to
IBIS models, available on the Analog Devices website,
