Note 1:
All voltages are measured with respect to the ground 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
that guarantee specific performance limits. This assumes that the device operates within the Operating Ratings. Specifications are not guaranteed for parameters
where no limit is given. The typical value, however, 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
allowable power dissipation is P

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 25C and represent the parametric norm.
Note 7:
Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 8:
The quiescent power supply current depends on the offset voltage when a practical load is connected to the amplifier.
