(Notes 1, 2, 8)
The following specifications apply for V
DD
= 3V and 8
load unless otherwise specified. Limits apply for T
A
=
25C. (Continued)
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 Characteristics
state DC andAC 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
,
θ
, and the ambient temperature T
. The maximum
allowable power dissipation is P
= (T

or the number given inAbsolute Maximum Ratings, whichever is lower. For the LM4895, see power derating
currents for additional information.
Note 4:
Human body model, 100pF discharged through a 1.5k
resistor.
Note 5:
Machine Model, 220pF–240pF discharged through all pins.
Note 6:
Typicals are measured at 25C and represent the parametric norm.
Note 7:
Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis.
Note 8:
For micro SMD only, shutdown current is measured in a Normal Room Environment. Exposure to direct sunlight will increase I
SD
by a maximum of 2μA.
Note 9:
Unterminated input.
Note 10:
10
terminated input.
Note 11:
When driving 4
loads from a 5V supply, the LM4895LD must be mounted to a circuit board.
