Electrical Characteristics for Bridged-Mode Operation
The following specifications apply for V
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 4: The maximum power dissipation is dictated by T
allowable power dissipation is P
Information section or the Absolute Maximum Ratings section.
Note 5: Human body model, 100pF discharged through a 1.5kΩ resistor.
Note 6: Machine model, 220pF–240pF discharged through all pins.
Note 7: The given θ
Note 8: The given θ
Note 9: The given θ
Note 10: The given θ
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: Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis.
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.
Note 16: When driving 3Ω or 4Ω loads and operating on a 5V supply, the LM4866LQ and LM4866MTE must be mounted to a circuit board that has a minimum of
2.5in
