Note 1: Absolute Maximum Ratings are those beyond which the life of the
device may be impaired.
Note 2: The P27/M27 and P81/M81 inputs are protected by ESD diodes to
the supply rails. If one of these four inputs goes outside the rails, the input
current should be limited to less than 10mA. The P9/M9 inputs can
withstand ±60V if P81/M81 are grounded and V
S
= ±15V (see Applications
Information section about “High Voltage CM Difference Amplifiers”).
Note 3: A heat sink may be required to keep the junction temperature
below absolute maximum ratings.
The ● denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at T
