Note 7:
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 50
).
Note 8:
All voltages are measured with respect to the ground pin, unless otherwise specified.
Note 9:
The given
θ
JA
and
θ
JC
is for an LM4851 mounted on a demonstration board with a 4 in
2
area of 1oz printed circuit board copper ground plane.
Note 10:
Please refer to the Output Noise vs Output Mode table in the Typical Performance Characteristics section for more details.
