Note 1:
Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating range indicates conditions for which the device is
intended to be functional, but does not guarantee specific performance limits. For guaranteed specifications and test conditions see Electrical Characteristics. The
guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed
test conditions.
Note 2:
V
TT
offset is the voltage measurement defined as V
TT
subtracted from V
REF
.
Note 3:
Load regulation is tested by using a 10ms current pulse and measuring V
TT
.
Note 4:
Quiescent current defined as the current flow into AVIN.
Note 5:
At elevated temperatures, devices must be derated based on thermal resistance. The device in the SO-8 package must be derated at
θ
JA
= 151 C/W
junction to ambient with no heat sink. The device in the LLP-16 must be derated at
θ
JA
= 51 C/W junction to ambient.
Note 6:
Limits are 100% production tested at 25C. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control
(SQC) methods. The limits are used to calculate National’s Average Outgoing Quality Level (AOQL).
Note 7:
The human body model is a 100pF capacitor discharged through a 1.5k
resistor into each pin.
