THERMAL REQUIREMENTS
All DATEL sampling A/D converters are fully characterized and specifi ed
over operating temperature (case) ranges of
0 to +70°C and –55 to +125°C. All room temperature

sinks or forced air cooling. Thermal impedance fi gures for each device
are listed in their respective specifi cation tables.
These devices do not normally require heat sinks, however, standard
precautionary design and layout procedures should be used to ensure
devices do not overheat. The ground and power planes beneath the
package, as well as all pcb signal runs to and from the device, should be
as heavy as possible to help conduct heat away from the package.

Electrically-insulating, thermally-conductive "pads" may be installed
underneath the package. Devices should be soldered to boards rather than
socketed, and of course, minimal air fl ow over the surface can greatly help
reduce the package temperature.
In more severe ambient conditions, the package/junction temperature of a
given device can be reduced dramatically (typically 35%) by using one of
DATEL's HS Series heat sinks. See Ordering Information for the assigned
part number. See page 1-183 of the DATEL Data Acquisition Components
Catalog for more information on the HS Series. Request DATEL Application
