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. Electrical Characteristics state 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 2:
All voltages are measured with respect to the relevant GND pin unless otherwise specified. All grounds should be coupled as close as possible to the
device.
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
or the number given in Absolute Maximum Ratings, whichever is lower. For the LM4931, see power
derating currents for more 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:
Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 8:
Best operation is achieved by maintaining 3.0V

.
Note 9:
Digital shutdown current is measured with system clock set for PLL output while the PLL is disabled.
Note 10:
Disabling or bypassing the PLL will result in an improvement in noise measurements.
Note 11:
Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis.
