For voltages beyond these limits, use input protection resistors. See the

Theory of Operation section for more information.

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.

PREDICTED LIFETIME VS. OPERATING

TEMPERATURE

Comprehensive reliability testing is performed on the AD8229.

Product lifetimes at extended operating temperature are obtained

using high temperature operating life (HTOL). Lifetimes are

predicted from the Arrhenius equation, taking into account

potential design and manufacturing failure mechanism assump-

tions. HTOL is performed to JEDEC JESD22-A108. A minimum

of three wafer fab and assembly lots are processed through

HTOL at the maximum operating temperature. Comprehensive

reliability testing is performed on all Analog Devices, Inc., high

temperature (HT) products.
