4 / 18 page Electrical Characteristics V DD = 2.6V (Notes 1, 2, 8) The following specifications apply for V DD = 2.6V and 8Ω Load unless otherwise specified. Limits apply for TA = 25˚C. Symbol Parameter Conditions LM4820-6 Units Typical Limit (Note 6) (Note 7) I DD Quiescent Power Supply Current V IN = 0V, Io = 0A 2.6 mA (max) I SD Shutdown Current V shutdown = GND 0.1 µA (max) P 0 Output Power ( 8 Ω ) Output Power ( 4 Ω ) THD = 1% (max);f=1kHz THD = 1% (max);f=1kHz 0.2 0.4 W W THD+N Total Harmonic Distortion+Noise P o = 0.1Wrms; f = 1kHz 0.08 % PSRR Power Supply Rejection Ratio V ripple = 200mV sine p-p 44 (f = 217Hz) 44 (f = 1kHz) dB A V Fixed Voltage Gain .5V in rms, RL =8Ω 6.0 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 Absolute Maximum Ratings, whichever is lower. For the LM4820-6, see power derating curves for additional 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: Typicals are measured at 25˚C and represent the parametric norm. Note 7: Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level). Note 8: For micro SMD only, shutdown current is measured in a Normal Room Environment. Exposure to direct sunlight will increase ISD by a maximum of 2µA. External Components Description (Figure 1) Components Functional Description 2. C i Input coupling capacitor which blocks the DC voltage at the amplifiers input terminals. Also creates a highpass filter with R i at fc = 1/(2π RiCi). Refer to the section, Proper Selection of External Components, for an explanation of how to determine the value of C i. 4. 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. 5. C B Bypass pin capacitor which provides half-supply filtering. Refer to the section, Proper Selection of External Components, for information concerning proper placement and selection of C B.
