Typical Audio Amplifier Application Circuit 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 Thermal Resistance θJA (WQFN) 140°C/W θJA (DGK) 210°C/W θJC (DGK) 56°C/W Soldering Information See AN-1187 (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 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. (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, 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 LM4923, see power derating curve for additional information. (4) Human body model, 100pF discharged through a 1.5k Ω resistor. (5) Machine Model, 220pF – 240pF discharged through all pins. 2 Submit Documentation Feedback Copyright © 2004–2009, Texas Instruments Incorporated Product Folder Links: LM4923 LM4923LQBD |
