ADSD-1410S
THERMAL REQUIREMENTS
The ADSD-1410S sampling A/D converter is fully characterized
and specified over the commercial operating temperature
(ambient) range of 0 to +70°C and military temperature range
of –55 to +125°C (EX suffix). All room-temperature (T
+25°C) production testing is performed without the use of heat
sinks or forced-air cooling. Thermal impedance figures for each
device are listed in their respective specification tables.
These devices do not normally require heat sinks, however,
standard precautionary design and layout procedures should

Notes:
➀ Outputs are enabled by either turning ENABLE A (Pin 10) or
ENABLE B (Pin 31) low for respective analog inputs A or B.
A high on both ENABLE A and ENABLE B results in disabling
the output bus (High Z).

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. Minimal air flow over the surface can
greatly help reduce the package temperature.
See timing diagram for details.
