Definitions

•

Specifications

 describe the performance of parameters covered by the product warranty 

(temperature –0 to 55 

°

C, unless otherwise noted.)

•

Typical

 describes additional product performance information that is not covered by the 

product warranty. It is performance beyond specification that 80% of the units exhibit 
with a 95% confidence level over the temperature range 20 to 30 

°

C. Typical 

performance does not include measurement uncertainty.

•

Nominal

 values indicate expected performance or describe product performance that is 

useful in the application of the product, but is not covered by the product warranty.

•

Characteristic Performance

 describes performance parameter that the product is 

expected to meet before it leaves the factory, but is not verified in the field and is not 
covered by the product warranty. A characteristic includes the same guard bands as a
