Note 1: All voltages are measured with respect to the ground pins, unless otherwise specified. All specifications are tested using the typical applicationas shown in
Figure 1.
Note 2: 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 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.For the LM4832, TJMAX = 150˚C, and the typical junction-to-ambient thermal resistance, when board
mounted, is 69˚C/W assuming the M28B package.
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 that all parts are tested in production to meet the stated values.
