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 LM4670, TJMAX = 150˚C.
The typical
θJA is 220˚C/W for the microSMD package and 64˚C/W for the LLP package.
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: 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 pin should
be driven as close as possible to GND for minimal shutdown current. See the Application Information section under SHUTDOWN FUNCTION for more information.
Note 10: The performance graphs were taken using the Audio Precision AUX-0025 Switching Amplifier Measurement Filter in series with the LC filter on the board.
Note 11: Typical output power numbers are for the LM4670 in the ITL (µSMD) package. In the LLP (SDA) package, the output power will be lower due to higher
resistance seen from the IC output pad to PCB trace. The difference increases with lower impedance loads.
Note 12: The maximum operating voltage for the LM4670 in the SDA (LLP) package when driving 4
Ω loads to greater than 10% THD+N is 5.0V.
