Note 1:
All voltages are measured with respect to the ground pins, 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 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 de-rated at elevated temperatures and is dictated by T
,
θ
, and the ambient temperature T
. The maximum
allowable power dissipation is P
= (T
-T
)/
θ
or the number given in the Absolute Maximum Ratings, whichever is lower. For the LM4780, T
JMAX
= 150C
and the typical
θ
JC
is 0.8C/W. Refer to the Thermal Considerations section for more information.
Note 4:
Human body model, 100pF discharged through a 1.5k
resistor.
Note 5:
Machine Model: a 220pF - 240pF discharged through all pins.
Note 6:
Typical specifications are measured at 25C and represent the parametric norm.
Note 7:
Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 8:
Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis.
Note 9:
The maximum operating junction temperature is 150C. However, the instantaneous Safe Operating Area temperature is 250C.
Note 10:
V
-
must have at least - 9V at its pin with reference to GND in order for the under-voltage protection circuitry to be disabled. In addition, the voltage
differential between V
and V
must be greater than 14V.
Note 11:
Cross talk performance was measured using the demo board shown in the datasheet. PCB layout will affect cross talk. It is recommended that input and
output traces be separated by as much distance as possible. Return ground traces from outputs should be independent back to a single ground point and use as
wide of traces as possible.
Note 12:
The output dropout voltage is defined as the supply voltage minus the clipping voltage. Refer to the Clipping Voltage vs. Supply Voltage graph in the
Typical Performance Characteristics
section.
Note 13:
The Differential Input Voltage Absolute Maximum Rating is based on supply voltages V
+
= 40V and V
-
= - 40V.
Note 14:
The TA27A is a non-isolated package. The package’s metal back, and any heat sink to which it is mounted are connected to the V
-
potential when using
only thermal compound. If a mica washer is used in addition to thermal compound,
θ
CS
(case to sink) is increased, but the heat sink will be electrically isolated from
V
.
Note 15:
DC electrical test.
