4 / 18 page Electrical Characteristics V DD =3V (Notes 1, 2) The following specifications apply for V DD = 3V, and RL =8 Ω + 33µH, measurement bandwidth is <10Hz - 22kHz unless oth- erwise specified. Limits apply for T A = 25˚C.

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 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 3: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the ambient temperature TA. The maximum allowable power dissipation is PDMAX =(TJMAX–TA)/θJA or the number given in Absolute Maximum Ratings, whichever is lower. For the LM4665, TJMAX = 150˚C. See the Efficiency and Power Dissipation versus Output Power curves for more information. Note 4: Human body model, 100 pF discharged through a 1.5 k Ω resistor. Note 5: Machine Model, 220 pF–240 pF discharged through all pins. Note 6: Typical specifications are specified at 25˚C and represent the parametric norm. Note 7: Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level). Note 8: Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis. Note 9: Shutdown current is measured in a normal room environment. Exposure to direct sunlight will increase ISD by a maximum of 2µA. The Shutdown Mode pin should be connected to VDD or GND and the Shutdown pin should be driven as close as possible to VDD or GND for minimum shutdown current and the best THD performance in PLAY mode. See the Application Information section under SHUTDOWN FUNCTION for more information. Note 10: The exposed-DAP of the LDA10B package should be electrically connected to GND. Note 11: The LM4665 in the micro SMD package (ITL) has an operating range of 2.7V - 3.8V for 8 Ω speaker loads. The supply range may be increased as speaker impedance is increased. It is not recommended that 4 Ω loads be used with the micro SMD package. To increase the supply voltage operating range, see Figure 2 and INCREASING SUPPLY VOLTAGE RANGE in the Application Information section for more information. External Components Description (Figure 1) Components Functional Description 1. C S Supply bypass capacitor which provides power supply filtering. Refer to the Power Supply Bypassing section for information concerning proper placement and selection of the supply bypass capacitor. www.national.com 4 |
