Note 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. The device is guaranteed to meet performance specification within 0℃ ~ +70℃ operating temperature
range and assured by design from –20℃ ~ +85℃.

Notes: With a load connected to the outputs the quiescent current will increase, the maximum value of this increase
being equal to the DC output offset voltage divided by RL.
