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 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 2:
The maximum power dissipation is dictated by T
JMAX
,
θ
JA
, and the ambient temperature T
A
and must be derated at elevated temperatures. The maximum
allowable power dissipation is P
DMAX
= (T

)/
θ

. For the LM4916, T
JMAX
= 150C. For the
θ

s, please see the Application Information section or the
Absolute Maximum Ratings section.
Note 3:
Human body model, 100pF discharged through a 1.5k
resistor.
Note 4:
Machine model, 220pF–240pF discharged through all pins.
Note 5:
All voltages are measured with respect to the ground (GND) pins unless otherwise specified.
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:
The quiescent power supply current depends on the offset voltage when a practical load is connected to the amplifier.
Note 9:
Output power is measured at the device terminals.
