Note 1:
Absolute Maximum Ratings are those values beyond which the life to V– + 0.4V, and the SEL pin is set to either V– + 0.4V or V– + 4V. At ±6V of a device may be impaired. and all other cases, DGND is set to ground and the ⎯E⎯N and SEL pins are
Note 2:
This parameter is guaranteed to meet specifi ed performance referenced from it. through design and characterization. It is not production tested.
Note 7:
The VREF pin is set to 3V when testing positive swing and –3V
Note 3:
As long as output current and junction temperature are kept when testing negative swing to ensure that the internal input clamps do below the Absolute Maximum Ratings, no damage to the part will occur. not limit the output swing. Depending on the supply voltage, a heat sink may be required.
