Note 1:
All voltages are measured with respect to the ground pin, unless otherwise specified.
Note 2:
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.
Electrical Characteristicsstate
DC and AC electrical specifications under particular test conditions which
guarantee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit
is given, however, the typical value is a good indication of device performance.
Note 3:
The maximum power dissipation must be derated at elevated temperatures and is dictated by T
JMAX
,
θ
JA
, and the ambient temperature T
A
. The maximum
allowable power dissipation is P
DMAX
= (T
JMAX
− T
A
)/θ
JA
. For the LM4882, T
JMAX
= 150˚C, and the typical junction-to-ambient thermal resistance, when board
mounted, is 210˚C/W for the MUA08A Package and 170˚C/W for the M08A Package.
Note 4:
Human body model, 100 pF discharged through a 1.5 kΩ resistor.
Note 5:
Typicals are measured at 25˚C and represent the parametric norm.
Note 6:
Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
