Note 1:
Applies to both single supply and split supply operation. Continuous short circuit operation at elevated ambient temperature and/or multiple Op Amp shorts
can result in exceeding the maximum allowed junction temperature of 150C. Output currents in excess of
±
30 mA over long term may adversely affect reliability.
Note 2:
The maximum power dissipation is a function of T

Note 3:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The
guaranteed specifications apply only for the test conditions listed.
Note 4:
Limits are guaranteed by testing or correlation.

Note 8:
A military RETS electrical test specification is available on request. At the time of printing, the LPC662AMJ/883 RETS specification complied fully with the
boldface
limits in this column. The LPC662AMJ/883 may also be procured to a Standard Military Drawing specification.
