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 (TA = +25°C) production testing is
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 the rising edge of the start convert pulse, which
may be as narrow as 20nsec. All production testing is performed
at a 1MHz sampling rate with 200nsec wide start pulses. For
lower sampling rates, wider start pulses may be used, however, a
minimum pulse width low of 20nsec 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.
