Note 3: Absolute Maximum Rating indicate limits beyond which damage to
the device may occur.
Note 4: Operating Ratings indicate conditions for which the device is func-
tional, but do not guarantee specific performance limits. For guaranteed
specifications and test conditions, see the Electrical Characteristics. The
guaranteed specifications apply only for the test conditions listed. Some
performance characteristics may degrade when the device is not operated
under the listed test conditions.
Note 5: Human body model, 100pF discharged through a 1.5k
resistor.
Note 6: Typical specifications are specified at +25C and represent the most
likely parametric norm.
Note 7: Datasheet min/max 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 dis-
charged directly into the IC with no external series resistor (resistance of
discharge path must be under 50
).
Note 9: All voltages are measured with respect to the ground pin, unless
otherwise specified.
Note 10: The given
θJA is for a LM4850LD with the Exposed-DAP soldered
to an exposed 1in2 area of 1oz printed circuit board copper.
Note 11: When driving 3
or 4 loads from a 5V supply, the LM4850 must
be mounted to a circuit board.
Note 12: Limits are guaranteed to National’s AOQL ( Average Outgoing
Quality Level ).
External Components Description
(Refer to Figure 1.)
Components
Functional Description
1.
R
i
Inverting input resistance which sets the closed-loop gain in conjunction with R
f. This resistor also forms a
high pass filter with C
i at fc = 1/(2πRiCi).
2.
C
i
Input coupling capacitor which blocks the DC voltage at the amplifier’s input terminals. Also creates a
highpass filter with R
i at fc = 1/(2πRiCi). Refer to the section, Proper Selection of External Components,
for an explanation of how to determine the value of C
i.
