3 / 20 page Electrical Characteristics for LM4651 (Notes 1, 2, 7) The following specifications apply for +V CC = +20V, −VEE = −20V, fSW = 125kHz, unless otherwise specified. Limits apply for T A = 25˚C. For specific circuit values, refer to Figure 1 (Typical Audio Application Circuit).

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 2: All voltages are measured with respect to the GND pin unless otherwise specified. Note 3: For operating at case temperatures above 25˚C, the LM4651 must be de−rated based on a 150˚C maximum junction temperature and a thermal resistance of θJA = 62 ˚C/W (junction to ambient), while the LM4652 must be de−rated based on a 150˚C maximum junction temperature and a thermal resistance of θJC = 2.0 ˚C/W (junction to case) for the isolated package (TF) or a thermal resistance of θJC = 1.0˚C/W (junction to case) for the non-isolated package (T). Note 4: Human body model, 100 pF discharged through a 1.5 k Ω resistor. Note 5: Machine Model, 220pF-240pF discharge through all pins. Note 6: The operating junction temperature maximum, Tjmax is 150˚C. Note 7: Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level). Note 8: The LM4652TA package TA15A is a non-isolated package, setting the tab of the device and the heat sink at −V potential when the LM4652 is directly mounted to the heat sink using only thermal compound. If a mica washer is used in addition to thermal compound, θCS (case to sink) is increased, but the heat sink will be isolated from −V. www.national.com 3 |
