Note 2: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Note 3: All voltages are measured with respect to the ground pin, unless otherwise specified.
Note 4: Human body model, 100pF discharged through a 1.5k
resistor.
Note 5: Typical specifications are specified at +25OC and represent the most likely parametric norm.
Note 6: Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 7: Datasheet max/min specification limits are guaranteed by design, test, or statistical analysis.
Note 8: Machine Model ESD test is covered by specification EIAJ IC-121-1981. A 200pF cap is charged to the specified voltage, then discharged directly into the
IC with no external series resistor (resistance of discharge path must be under 50Ohms).
Note 9: The given
θJA is for an LM4810 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 LM4810 packaged in an LDA08B with the Exposed-Dap not soldered to any circuit board copper.
