OUTPUT DRIVE
Normally all ADC71 logic outputs will drive two standard
TTL loads; however, if long digital lines must be driver,
external logic buffers are recommended.
HEAT DISSIPATION
The ADC71 dissipates approximately 0.6W (typical) and the
packages have a case-to-ambient thermal resistance (
θ
) of
25
°
C/W. For operation above 85
°
C,
θ
should be lowered
by a heat sink or by forced air over the surface of the
package. See Figure 10 for
θ
requirement above 85
°
C. If
the converter is mounted on a PC card, improved thermal
contact with the copper ground plane under the case can be
achieved using a silicone heat sink compound. On a 0.062"
thick PC card with a 16 square in (min) area, this techniques
will allow operation to 85
°
C.
