1

Maximum output voltage drift is guaranteed for all packages.

2

3

The long-term stability specification is noncumulative. The drift in subsequent 1,000 hour periods is significantly lower than in the first 1,000 hour period.

4

The operating temperature range is defined as the temperature extremes at which the device will still function. Parts may deviate from their specified performance

outside their specified temperature range.
