ADSP-BF538/ADSP-BF538F
OUTPUT DRIVE CURRENTS
Figure 30 through Figure 37 on Page 45 shows typical current-
voltage characteristics for the output drivers of the ADSP-
BF538/ADSP-BF538F processors. The curves represent the cur-
rent drive capability of the output drivers as a function of output
voltage.
