ADSP-TS101S

OUTPUT DRIVE CURRENTS

Figure 21 through Figure 28 show typical I–V characteristics for

the output drivers of the ADSP-TS101S. The curves in these dia-

grams 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,

www.analog.com.
