For MIL-STD components, please refer to LTC 883C data sheet for test
listing and parameters.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Offset voltage measured with high speed test equipment,
approximately 1second after power is applied.
Note 3: This parameter is tested on a sample basis only.
Note 4: Long Term Input Offset Voltage Stability refers to the averaged
trend line of V_OS versus Time over extended periods after the first 30 days
of operation. Excluding the initial hour of operation, changes in V_OS during
the first 30 operating days are typically 2.5µV.
Note 5: Parameter is guaranteed by design.
Note 6: 10Hz noise voltage density is sample tested on every lot.
Devices 100% tested at 10Hz are available on request.
Note 7: The V + supply terminals are completely independent and may be
powered by separate supplies if desired (this approach, however, would
sacrifice the advantages of the power supply rejection ratio matching). The
V – supply terminals are both connected to the common substrate and
must be tied to the same voltage. Both V – pins should be used.
