DATEL
THERMAL REQUIREMENTS
All DATEL sampling A/D converters are fully characterized and speci-
fi ed over operating temperature (case) ranges of 0 to +70°C and –55
to +125°C. All room-temperature (T
performed without the use of heat sinks or forced-air cooling. Thermal
impedance fi gures for each device are listed in their respective specifi ca-
tion tables.
These devices do not normally require heat sinks; however, standard
precautionary design and layout procedures should be used to ensure

are triggered by both the rising and falling edges of the start
convert pulse. When sampling at 1MHz, the start pulse must be
between 175 and 225nsec wide. For lower sampling rates, wider
start pulses may be used, however, a minimum pulse width low of
50nsec must be maintained.

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.
