Note 3: The
θJA given is for an MXA28A package whose exposed-DAP is soldered to an exposed 2in 2 piece of 1 ounce printed circuit board copper.
Note 4: The
θJA given is for an MXA28A package whose exposed-DAP is soldered to a 2in2 piece of 1 ounce printed circuit board copper on a bottom side layer
through 21 8mil vias.
Note 5: The
θJA given is for an MXA28A package whose exposed-DAP is soldered to an exposed 1in 2 piece of 1 ounce printed circuit board copper.
Note 6: The
θJA given is for an MXA28A package whose exposed-DAP is not soldered to any copper.
Note 7: The given
θJA is for an LM4836 packaged in an LQA24A with the exposed-DAP soldered to an exposed 2in2 area of 1oz printed circuit board copper.
Note 8: All voltages are measured with respect to the ground pins, unless otherwise specified. All specifications are tested using the typical application as shown
in Figure 2.
Note 9: When driving 3
loads and operating on a 5V supply the LM4836MTE exposed DAP must be soldered to the circuit board and forced-air cooled.
Note 10: When driving 4
loads and operating on a 5V supply the LM4836MTE exposed DAP must be soldered to the circuit board.
Note 11: When driving 3
or 4 loads and operating on a 5V supply, the LM4836LQ must be mounted to the circuit board that has a minimum of 2.5in2 of exposed,
uninterrupted copper area connected to the LLP package’s exposed DAP.
Note 12: 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 13: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, θ JA, and the ambient temperature TA. The maximum
allowable power dissipation is PDMAX =(TJMAX TA )/θJA. For the LM4836, TJMAX = 150C. The typical junction-to-ambient thermal resistance, when board mounted,
is 80C/W for the MTC28 package, 41C/W for the MXA28A package, and 42C/W for the LQA028AA package.
Note 14: Human body model, 100 pF discharged through a 1.5 k
resistor.
Note 15: Machine Model, 220 pF–240 pF discharged through all pins.
Note 16: Typicals are measured at 25C and represent the parametric norm.
Note 17: Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis.
