Bump Description (continued) Bump Name Description E5 LSOUTL- Left Loudspeaker Inverting Output F1 CPGND Charge Pump Ground F2 HPVDD Headphone Power Supply F3 CPVSS Charge Pump Output F4 VDD Loudspeaker Power Supply F5 LSOUTL+ Left Loudspeaker Non-Inverting Output 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) (3) VDD, I 2CV DD 6V Supply Voltage(1) HPVDD 3V Storage Temperature −65°C to +150°C Input Voltage −0.3V to VDD +0.3V Power Dissipation(4) Internally Limited ESD HBM(5) 2000V ESD MM(6) 150V ESD CDM(7) 750V Junction Temperature 150°C Thermal Resistance θJA (TLA30B1A) 90°C/W Soldering Information: See AN-1112 (Literature Number SNVA009) (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The Recommended Operating Conditions indicate conditions at which the device is functional and the device should not be operated beyond such conditions. All voltages are measured with respect to the ground pin, unless otherwise specified (2) The Electrical Characteristics tables list specified specifications under the listed Recommended Operating Conditions except as otherwise modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not ensured. (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. (5) Human body model, applicable std. JESD22-A114C. (6) Machine model, applicable std. JESD22-A115-A. (7) Charge device model, applicable std. JESD22–C101D. Operating Ratings Temperature Range (TMIN ≤ TA ≤ TMAX) −40°C ≤ TA ≤ +85°C VDD 2.7V ≤ VDD ≤ 5.5V Supply Voltage HPVDD 1.6V ≤ HPVDD ≤ 2.0V I2CDD 1.7V ≤ I2CVDD ≤ 5.5V Copyright © 2011–2013, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Links: LM49251 |
