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

+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

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.

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).

See timing diagram for details.
