Electrical
Environmental
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
THERMAL RESISTANCE
The heat sink of the AD6645ASVZ, 52-lead TQFP_EP (SV-52-1)
package must be soldered to the PCB GND plane to meet thermal
specifications.
