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
θ
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
θ
JA
is for an LM4810 packaged in an LDA08B with the Exposed-Dap not soldered to any circuit board copper.
