3 / 13 page ![]() Electrical Characteristics (Notes 2, 3) The following specifications apply for V DD = 3.3V unless otherwise specified, limits apply to TA = 25˚C. Symbol Parameter Conditions Conditions Units (Limits) Typ (Note 7) Limit (Note 8) I DD Supply Current V IN = 0V, IO = 0A 1.0 mA (max) V OS Input Offset Voltage V IN = 0V 7 mV (max) P o Output Power THD+N = 0.1%,f=1kHz R L =16Ω 40 mW R L =32Ω 28 mW THD+N = 10%,f=1kHz R L =16Ω 56 mW R L =32Ω 38 mW Electrical Characteristics (Notes 2, 3) The following specifications apply for V DD = 2.6V unless otherwise specified, limits apply to TA = 25˚C. Symbol Parameter Conditions Conditions Units (Limits) Typ (Note 7) Limit (Note 8) I DD Supply Current V IN = 0V, IO = 0A 0.9 mA (max) V OS Input Offset Voltage V IN = 0V 5 mV (max) P o Output Power THD+N = 0.1%,f=1kHz R L =16Ω 20 mW R L =32Ω 16 mW THD+N = 10%,f=1kHz R L =16Ω 31 mW R L =32Ω 22 mW Note 2: All voltages are measured with respect to the ground pin, unless otherwise specified. Note 3: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is func- tional, but do not guarantee specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which guar- antee 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 must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the ambient temperature TA. The maximum allowable power dissipation is P DMAX =(TJMAX −TA)/ θJA. For the LM4808, TJMAX = 150˚C, and the typical junction-to-ambient thermal resistance, when board mounted, is 210˚C/W for the MSOP Package and 107˚C/W for package N08E. 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: Typicals are measured at 25˚C and represent the parametric norm. Note 8: Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level). www.national.com 3 |
