3 / 34 page LM4938 www.ti.com SNAS245B – FEBRUARY 2005 – REVISED MAY 2013 These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. Absolute Maximum Ratings (1) (2) Supply Voltage 6.0V Storage Temperature -65°C to +150°C Input Voltage −0.3V to VDD +0.3V Power Dissipation(3) Internally limited ESD Susceptibility(4) 2000V ESD Susceptibility(5) 200V Junction Temperature 150°C Vapor Phase (60 sec.) 215°C Soldering Information Small Outline Package Infrared (15 sec.) 220°C θJC (typ) - PWP0028A 2°C/W θJA (typ) - PWP0028A (HTSSOP) (6) 41°C/W θJA (typ) - PWP0028A (HTSSOP) (7) 54°C/W θJA (typ) - PWP0028A (HTSSOP) (8) 59°C/W θJA (typ) - PWP0028A(HTSSOP) (9) 93°C/W (1) 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 performance. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. (3) 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 LM4938, TJMAX = 150°C, and the typical junction-to- ambient thermal resistance for each package can be found in the Absolute Maximum Ratings()() section above. (4) Human body model, 100pF discharged through a 1.5k Ω resistor. (5) Machine Model, 200pF – 220pF discharged through all pins. (6) The θJA given is for an PWP0028A package whose HTSSOP is soldered to an exposed 2in 2 piece of 1 ounce printed circuit board copper. (7) The θJA given is for an PWP0028A package whose HTSSOP is soldered to a 2in 2 piece of 1 ounce printed circuit board copper on a bottom side layer through 21 8mil vias. (8) The θJA given is for an PWP0028A package whose HTSSOP is soldered to an exposed 1in 2 piece of 1 ounce printed circuit board copper. (9) The θJA given is for an PWP0028A package whose HTSSOP is not soldered to any copper.
