Note 1:
All voltages are measured with respect to the GND pin unless otherwise specified.
Note 2:
: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device
is functional but do not guarantee specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions
which guarantee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters
where no limit is given, however, the typical value is a good indication of device performance.
Note 3:
: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX,
θ
JA, and the ambient temperature, TA. The
maximum allowable power dissipation is P
DMAX = (TJMAX - TA)/ θJA or the number given in Absolute Maximum Ratings, whichever is lower. For the LM4911, see
power derating currents for more information.
Note 4:
Human body model, 100pF discharged through a 1.5k
resistor.
Note 5:
Machine Model, 220pF-240pF discharged through all pins.
Note 6:
Typicals are measured at 25°C and represent the parametric norm.
Note 7:
Limits are guaranteed to National's AOQL (Average Outgoing Quality Level).
Note 8:
Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis.
Note 9:
10 Terminated input.
Note 10:
The LDA10A package has its exposed-DAP soldered to an exposed 1.2in2 area of 1oz. Printed circuit board copper.
Note 11:
The limit is guaranteed over the temperature range of –40°C to +85°C.
External Components Description
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 high-pass
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.
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 Proper
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 R
L at
f
o = 1/(2πRLCo)
