Excluding the initial hour of operation, changes in VOS during listing and parameters. the first 30 operating days are typically 2.5µV.
Note 1:
Absolute Maximum Ratings are those values beyond which the life
Note 5:
Parameter is guaranteed by design. of a device may be impaired.
Note 6:
10Hz noise voltage density is sample tested on every lot.
Note 2:
Offset voltage measured with high speed test equipment, Devices 100% tested at 10Hz are available on request. approximately 1second after power is applied.
Note 7:
The V + supply terminals are completely independent and may be
Note 3:
This parameter is tested on a sample basis only. powered by separate supplies if desired (this approach, however, would
Note 4:
Long Term Input Offset Voltage Stability refers to the averaged sacrifice the advantages of the power supply rejection ratio matching). The trend line of V V – supply terminals are both connected to the common substrate and OS versus Time over extended periods after the first 30 days must be tied to the same voltage. Both V – pins should be used. 1002fb 4
