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 ensure specific performance limits. Electrical Characteristics state DC and AC electrical

specifications under particular test conditions which ensure specific performance limits. This assumes that the device operates within the

Operating Ratings. Specifications are not ensured for parameters where no limit is given. The typical value however, is a good indication

of device performance.

(2)

All voltages are measured with respect to the ground (GND) pins, unless otherwise specified.

(3)

Typicals are specified at 25°C and represent the parametric norm.

(4)

Datasheet min/max specification limits are ensured by design, test, or statistical analysis.

(5)

The quiescent power supply current depends on the offset voltage when a practical load is connected to the amplifier.
