ADSP-TS201S
OUTPUT DRIVE CURRENTS
through
show typical I–V characteristics for
the output drivers of the ADSP-TS201S 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. Typical drive currents for intermediate temper-
atures (such as 85°C) should be obtained from the curves using
linear interpolation. For complete output driver characteristics,
refer to the DSP’s IBIS models, available on the Analog Devices
website (
).
