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
θJA and θJC is for an LM4851 mounted on a demonstration board witha4in2 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.

Functional Description
1.
C
in
This is the input coupling capacitor. It blocks the DC voltage at, and couples the the input signal to, the
amplifier’s input terminals. C
i, also creates a highpass filter with the internal resistor Ri at fc = 1/(2
πR
iCi).
2.
C
s
This is the supply bypass capacitor. It provides power supply filtering.
3.
C
B
This is the BYPASS pin capacitor. It provides half-supply filtering.
