3 / 23 page LM4954 www.ti.com SNAS292B – JUNE 2005 – REVISED APRIL 2013 Absolute Maximum Ratings (1) (2) (3) Supply Voltage(1) 9.5V Storage Temperature −65°C to +150°C Input Voltage −0.3V to VDD +0.3V Power Dissipation(4) Internally Limited ESD Susceptibility(5) 2000V ESD Susceptibility(6) 200V Junction Temperature 150°C Thermal Resistance θJA (DSBGA) (7) 180°C/W Soldering Information See AN-112 (SNAA002) “DSBGA Wafers Level Chip Scale Package.” (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 performance. (3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications. (4) 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 or the number given in Absolute Maximum Ratings, whichever is lower. For the LM4954, see power derating curves for additional information. (5) Human body model, 100pF discharged through a 1.5k Ω resistor. (6) Machine Model, 220pF – 240pF discharged through all pins. (7) All bumps have the same thermal resistance and contribute equally when used to lower thermal resistance. The θJA given in the Absolute Maximum Ratings section under Thermal Resistance is for the ITL package without any heat spreading planes on the PCB. Operating Ratings (1) (2) Temperature Range TMIN ≤ TA ≤ TMAX −40°C ≤ TA ≤ 85°C Supply Voltage 2.7V ≤ VDD ≤ 9V (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 performance.
