Note 2:
An LM4913MH that has been properly mounted to a circuit board with a copper heatsink area of at least 2in
2
will deliver 2.1W into 4
.
Note 3:
All voltages are measured with respect to the ground pin, unless otherwise specified.
Note 4:
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 5:
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

or the number given inAbsolute Maximum Ratings, whichever is lower. For the LM4913, see power derating
curves for additional information.
Note 6:
Human body model, 100pF discharged through a 1.5k
resistor.
Note 7:
Machine Model, 220pF–240pF discharged through all pins.
Note 8:
The given
θ
JA
is for an LM4913 packaged in an MXF10A with the Exposed-DAP soldered to an exposed 2in
2
area of 1oz printed circuit board copper.
Note 9:
Typicals are measured at 25C and represent the parametric norm.
Note 10:
Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 11:
Datasheet minimum and maximum specification limits are guaranteed by design, test, or statistical analysis.
Note 12:
Output power is measured at the amplifier’s package pins.
Note 13:
When driving 4
loads and operating on a 5V supply, the LM4913MH must be mounted to a circuit board that has a minimum of 2.5in
2
of exposed,
uninterrupted copper area connected to the MH package’s exposed DAP.
Note 14:
