Note 3:
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 operates within the Operating Ratings. Specifications are not guaranteed for parameters where
no limit is given. The typical value however, is a good indication of device performance.
Note 4:
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
. For the LM4867, T
JMAX
= 150˚C. For the
θ
JA
s for different packages, please see the Application
Information section or the Absolute Maximum Ratings section.

Note 13:
All voltages are measured with respect to the ground (GND) pins, unless otherwise specified.
Note 14:
Typicals are measured at 25˚C and represent the parametric norm.
Note 15:
Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level). Datasheet min/max specification limits are guaranteed by design, test, or
statistical analysis.
Note 16:
The quiescent power supply current depends on the offset voltage when a practical load is connected to the amplifier.
Note 17:
Output power is measured at the device terminals.
Note 18:
When driving 3Ω loads from a 5V supply, the LM4867LQ, LM4867MTE, or LM4867MTE-1 must be mounted to the circuit board and forced-air cooled (450
linear-feet per minute).
Note 19:
When driving 4Ω loads from a 5V supply, the LM4867LQ, LM4867MTE or LM4867MTE-1 must be mounted to the circuit board.
