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 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 4:
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
JMAX
T
A
)/
θ
JA
. For the LM4866, T
JMAX
= 150C. For the
θ
JA
s for different packages, please see the Application
Information section or the Absolute Maximum Ratings section.
Note 5:
Human body model, 100pF discharged through a 1.5k
resistor.
Note 6:
Machine model, 220pF–240pF discharged through all pins.
Note 7:
The given
θ
JA
is for an LM4866 packaged in an LQA24A with the exposedDAP soldered to an exposed 2in
2
area of 1oz printed circuit board copper.
Note 8:
The given
θ
JA
is for an LM4866 packaged in an MXA20A with the exposedDAP soldered to an exposed 2in
2
area of 1oz printed circuit board copper.
Note 9:
The given
θ
JA
is for an LM4866 packaged in an MXA20A with the exposedDAP soldered to an exposed 1in
2
area of 1oz printed circuit board copper.
Note 10:
The given
θ
JA
is for an LM4866 packaged in an MXA20A with the exposedDAP not soldered to prinbted circuit board copper.
Note 11:
All voltages are measured with respect to the ground (GND) pins unless otherwise specified.
Note 12:
Typicals are measured at 25C and represent the parametric norm.
Note 13:
Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis.
Note 14:
The quiescent power supply current depends on the offset voltage when a practical load is connected to the amplifier.
Note 15:
Output power is measured at the device terminals.
Note 16:
When driving 3
or 4
loads and operating on a 5V supply, the LM4866LQ and LM4866MTE must be mounted to a circuit board that has a minimum of
2.5in
of exposed, uninterrupted copper area connected to the package’s exposed DAP.
