Note 1:
“Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device
is functional, but do not guarantee specific performance limits.
Note 2:
These specifications apply for 0°C
≤ T
A ≤ +70°C for the LM329 unless otherwise specified. The maximum junction temperature for a LM329 is 100°C.
For operating at elevated temperature. The TO-92 package, the derating is based on 180°C/W junction to ambient with 0.4″ leads from a PC board and 160°C/
W junction to ambient with 0.125″ lead length to a PC board.
Note 3:
These changes are tested on a pulsed basis with a low duty-cycle. For changes versus temperature, compute in terms of tempco.
