Components
Functional Description
3.
R
f
Feedback resistance which sets the closed-loop gain in conjunction with R
i.
4.
C
s
Supply bypass capacitor which provides power supply filtering. Refer to the Power Supply Bypassing
section for information concerning proper placement and selection of the supply bypass capacitor.
5.
C
B
Bypass pin capacitor which provides half-supply filtering. Refer to the section, Proper Selection of
External Components, for information concerning proper placement and selection of C
B.
6.
C
O
Output coupling capacitor which blocks the DC voltage at the amplifier’s output. Forms a high pass filter
with the single-ended load R
L at fO = 1/(2π RLCO).

Note 13: This curve shows the LM4850LD’s thermal dissipation ability at different ambient temperatures given the exposed-DAP of the part is soldered to a plane
of 1oz. Cu with an area given in the label of each curve. This label also designated whether the plane exists on the same (top) layer as the chip, on the bottom layer,
or on both layers. Infinite heatsink and unattached (no heatsink) conditions are also shown.
