Note 1: All voltages are measured with respect to the ground pin, 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 and AC 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 derated at elevated temperatures and is dictated by T
JMAX
, θ

, and the ambient temperature T
A
. The maximum
allowable power dissipation is P

or the number given in the Absolute Maximum Ratings, whichever is lower. For the LM4864, T

The typical junction-to-ambient thermal resistance, when board mounted, is 230˚C/W for package number MUA08A, 170˚C/W for package number M08A and is
107˚C/W for package number N08E

Note 4: Human body model, 100pF discharged through a 1.5kΩ resistor.
Note 5: Machine Model, 220pF – 240pF discharged through all pins.
Note 6: Typicals are measured at 25˚C and represent the parametric norm.
Note 7: 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 quiescent power supply current depends on the offset voltage when a practical load is connected to the amplifier.
Note 10: The MUA08BA package is thermally limited to 595 mW of power dissipation at room temperature. Refering to the Power Dissipation vs Output Power
graph in the Typical Performance Characteristics section, the power dissipation limitation for the package occurs at 300 mW of output power. This package
limitation is based on 25˚C ambient temperature and θ
JA
= 210˚C. For higher output power possibilities refer to the Power Dissipation Section.
Note 11: The LDA10A package has its exposed-DAP soldered to an exposed 1.2in
2
area of 1oz printed circuit board copper.
