(1)
All voltages are measured with respect to the ground pin, unless otherwise specified.
(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's performance.
(3)
Typical specifications are specified at 25°C and represent the parametric norm.
(4)
Tested limits are guaranteed to National's AOQL (Average Outgoing Quality Level).
(5)
Datasheet min/max specification limits are guaranteed by designs, test, or statistical analysis.
(6)
The shutdown pin (pin1) should be driven as close as possible to VDD for minimum current in Shutdown Mode.
External Components Description
(Figure 1)
Components
Functional Description
1.
Ri
Combined with Rf, this inverting input resistor sets the closed-loop gain. Ri also forms a high pass filter with Ci at fc =
1/(2
πRiCi).
2.
Ci
This input coupling capacitor blocks DC voltage at the amplifier's terminals. Combined with Ri, it creates a high pass
filter with Ri at fc = 1/(2πRiCi). Refer to the section, Proper Selection of External Components for an explanation of
how to determine the value of Ci.
3.
Rf
Combined with Ri, this is the feedback resistor that sets the closed-loop gain: Av = 2(RF/Ri).
4.
CS
This is the power supply bypass capacitor that filters the voltage applied to the power supply pin. Refer to the
Application Information section for proper placement and selection of Cs.
5.
CB
This is the bypass pin capacitor that filters the voltage at the BYPASS pin. Refer to the section, Proper Selection of
External Components, for information concerning proper placement and selection of CB.
