Operating Ratings Temperature Range T MIN ≤ T A ≤ T MAX −40˚C ≤ T A ≤ +85˚C Supply Voltage 2.0V ≤ V DD ≤ 5.5V Thermal Resistance θ JC (typ) — M08A 35˚C/W θ JA (typ) — M08A 140˚C/W θ JC (typ) — N08E 37˚C/W θ JA (typ) — N08E 107˚C/W Electrical Characteristics (Note 1) (Note 2) The following specifications apply for V DD = 5V, unless otherwise specified. Limits apply for TA = 25˚C. Symbol Parameter Conditions LM4861 Units (Limits) Typical Limit (Note 6) (Note 7) V DD Supply Voltage 2.0 V (min) 5.5 V (max) I DD Quiescent Power Supply Current V IN = 0V, IO = 0A (Note 8) 6.5 10.0 mA (max) I SD Shutdown Current V pin1 =VDD 0.6 10.0 µA (max) V OS Output Offset Voltage V IN = 0V 5.0 50.0 mV (max) P O Output Power THD = 1% (max);f=1kHz 1.1 1.0 W (min) THD+N Total Harmonic Distortion + Noise P O = 1Wrms; 20 Hz ≤ f ≤ 20 kHz 0.72 % PSRR Power Supply Rejection Ratio V DD = 4.9V to 5.1V 65 dB Note 1: All voltages are measured with respect to the ground pin, unless otherwise specified. 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 the Absolute Maximum Ratings, whichever is lower. For the LM4861, TJMAX = 150˚C, and the typical junction-to-ambient thermal resistance, when board mounted, is 140˚C/W. Note 4: Human body model, 100pF discharged through a 1.5k Ω resistor. Note 5: Machine Model, 220pF–240pF discharged through all pins. Note 6: Typicals are measured at 25˚C and represent the parametric norm. Note 7: Limits are guaranteed to Nationai’s AOQL (Average Outgoing Quality Level). Note 8: The quiescent power supply current depends on the offset voltage when a practical load is connected to the amplifier. www.national.com 3 |
