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 Conditionsindicate 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 TI 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 2.4V ≤ VDD ≤ 5.5V (1) “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability and/or performance. 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 Conditionsindicate 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. Electrical Characteristics VDD = PVDD = 5V (1) (2) The following specifications apply for AV = 12dB, (RL = 8Ω, SYNC_IN = VDD (Spread Spectrum mode), f = 1kHz, unless otherwise specified. Limits apply for TA = 25°C.

Typical specifications are estimations only and are not ensured. (2) RL is a resistive load in series with two inductors to simulate an actual speaker load. For RL = 8Ω, the load is 15µH + 8Ω, +15µH. For RL = 4 Ω, the load is 15µH + 4Ω + 15µH. (3) Typical values represent most likely parametric norms at TA = +25°C, and at the Recommended Operation Conditions at the time of product characterization and are not specified. (4) Datasheet min/max specification limits are specified by test or statistical analysis. 4 Submit Documentation Feedback Copyright © 2007–2009, Texas Instruments Incorporated Product Folder Links: LM48310 |
