The. denotes the specifications which apply over the full operating temperature range.

For MIL-STD components, please refer to LTC 883C data sheet for test listing and parameters.

Nole 1: Offset voltage measured with high speed test equipment, approximately 1 second after power is applied.

No Ie 2: This parameter is tested on a sample basis only.

Note 3: Long Term Input Offset Voltage Stability refers to the averaged trend line of Vos versus Time over extended periods after the first 30 days of operation. Excluding the initial hour of operation, changes in Vos during the first 30 operating days are typically 2.5/l V.
