Electrical Characteristics (Continued)

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 T

, θ , and the ambient temperature, T . The maximum

JMAX JA

allowable power dissipation is P

= (T

− T ) / θ or the given in Absolute Maximum Ratings, whichever is lower.

DMAX

JMAX A JA

Note 4: Human body model, 100pF discharged through a 1.5kΩ 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: Shutdown current is measured in a normal room environment. The Shutdown pin should be driven as close as possible to Vin for minimum shutdown

current.

Note 10: Temperature range is tentative, pending characterization.

Note 11: An amplifier supply voltage of 9.0V can only be obtained when the over current and over voltage protection circuitry is disabled (OV/OC Detect pin is

disabled).

Note 12: The value for a θ is measured with the LM4962 mounted on a 3” x 1.5” 4 layer board. The copper thickness for all 4 layers is 0.5oz (roughly 0.18mm).
