RELIABILITY DATA  
R3  
Extensive reliability testing has been performed on the  
OPA621. Accelerated life testing (2000 hours) at maximum  
operating temperature was used to calculate MTTF at an  
ambient temperature of 25°C. These test results yield MTTF  
of: DIP = 5.02E+7 Hours, and SO-8 = 2.94E+7 Hours.  
Additional tests such as PCT have also been performed.  
Reliability reports are available upon request for each of the  
package options offered.

ENVIRONMENTAL (Q) SCREENING

The inherent reliability of a semiconductor device is  
controlled by the design, materials and fabrication of the  
device—it cannot be improved by testing. However, the use  
of environmental screening can eliminate the majority of  
those units which would fail early in their lifetimes (infant  
mortality) through the application of carefully selected  
accelerated stress levels. Burr-Brown “Q-Screening” pro-  
vides environmental screening to our standard industrial  
products, thus enhancing reliability. The screening illus-  
trated in the following table is performed to selected levels  
similar to those of MIL-STD-883.

Demonstration boards are available to speed protyping. The  
8-pin DIP packaged parts may be evaluated using the DEM-  
OPA65XP board while the SO-8 packaged part may be  
evaluated using the DEM-OPA65XU board. Both of these  
boards come partially assembled from your local distributor  
(the external resistors or the amplifier is not included).
