4 / 42 page LM49450 SNAS440D – FEBRUARY 2008 – REVISED MAY 2013 www.ti.com Absolute Maximum Ratings (1) (2) (3) Supply Voltage(1) 6.0V 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 (TJMAX) 150°C Thermal Resistance θJC 2.4°C/W θJA 28.4°C/W (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 ensured 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. Operating Ratings (1) (2) Temperature Range TMIN ≤ TA ≤ TMAX −40°C ≤ TA ≤ +85°C Supply Voltage 2.7V ≤ VDD ≤ 5.5V (VDD, LSVDD) Headphone Supply Voltage 1.8V ≤ VDD ≤ 2.7V (CPVDD, HPVDD) Digital Core Supply Voltage (DVDD) 2.7V ≤ DVDD ≤ 4.5V Digital IO Supply Voltage (IOVDD) 1.8V ≤ IOVDD ≤ 4.5V (1) “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability and/or performance.
