NOTES
1
Maximum output voltage drift is guaranteed for all packages.
2
3.0 V mode typically adds 100
µA
to the quiescent current. Also, Iq increases by 2
µA/V
above an input voltage of 5 V.
3
The long term stability specification is noncumulative. The drift in subsequent 1000 hr. periods is significantly lower than in the first 1000 hr. 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.
*Same as AD780AN/AR specification.
Specifications subject to change without notice.
