Note 3: 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 11: All voltages are measured with respect to the ground (GND) pins unless otherwise specified.

Note 12: Typicals are measured at 25˚C and represent the parametric norm.

Note 13: Limits are guaranteed to Kingbor’s AOQL (Average Outgoing Quality Level).

Note 14: The quiescent power supply current depends on the offset voltage when a practical load is connected to the amplifier.

Note 15: Output power is measured at the device terminals.
