(1) All voltages are measured with respect to the ground pin, unless otherwise specified.

(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 ensure specific performance limits. Electrical Characteristics state DC and AC electrical

specifications under particular test conditions which ensure specific performance limits. This assumes that the device is within the

Operating Ratings. Specifications are not ensured for parameters where no limit is given. However, the typical value is a good indication

of device's performance.

(3) If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.

(4) The maximum power dissipation must be derated at elevated temperatures and is dictated by T_JMAX, θ_JA, and the ambient temperature

T_A. The maximum allowable power dissipation is P_DMAX= (T_JMAX–T_A)/θ_JA. For the LM4819, T_JMAX= 150°C and the typical junction-to-

ambient thermal resistance (θ_JA) when board mounted is 210°C/W for the VSSOP package and 170°C/W for the SOIC package.

(5) Human body model, 100pF discharged through a 1.5 kΩ resistor.

(6) Machine Model, 220pF–240pF capacitor is discharged through all pins.

(7) The given θ_JAis for an LM4819 package in an NGL0008B with the Exposed-DAP soldered to a printed circuit board copper pad with an

area equivalent to that of the Exposed-DAP itself. The Exposed-DAP of the NGL0008B package should be electrically connected to

GND or an electrically isolated copper area.

(8) The given θ_JAis for an LM4819 package in an NGL0008B with the Exposed-DAP not soldered to any printed circuit board copper.
