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 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 5: Human body model, 100 pF discharged through a 1.5 k

Ω resistor.

Note 6: Machine model, 220 pF–240 pF discharged through all pins.

Note 7: All voltages are measured with respect to the ground (GND) pins, unless otherwise specified.

Note 8: Typicals are specified at 25˚C and represent the parametric norm.

Note 9: Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis.

Note 10: The quiescent power supply current depends on the offset voltage when a practical load is connected to the amplifier.

Note 11: Output power is measured at the device terminals.

Note 12: When driving 3

uninterrupted copper area connected to the SQ package’s exposed DAP.

Note 13: All measurements taken from Applications Diagram (Figure 3).
