Note 2: All voltages are measured with respect to the ground pin, unless otherwise specified.
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 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 must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the ambient temperature TA. The maximum
allowable power dissipation is P DMAX =(TJMAX TA)/ θJA. For the LM4808, TJMAX = 150C, and the typical junction-to-ambient thermal resistance, when board
mounted, is 210C/W for package MUA08A and 170C/W for package M08A.
Note 5: Human body model, 100 pF discharged through a 1.5 k
resistor.
Note 6: Machine Model, 220 pF–240 pF discharged through all pins.
Note 7: Typicals are measured at 25C and represent the parametric norm.
Note 8: Tested 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 9: The given
θ
JA is for an LM4808 packaged in an LDA08B with the Exposed-DAP soldered to a printed circuit board copper pad with an area equivalent to
that of the Exposed-DAP itself.
Note 10: The given
θJA is for an LM4808 packaged in an LDA08B with the Exposed-DAP not soldered to any printed circuit board copper.
