10 / 108 page LM49350, LM49350RLEVAL SNAS359D – SEPTEMBER 2008 – REVISED JUNE 2012 www.ti.com OPERATING RATINGS Temperature Range −40°C to +85°C Supply Voltage A_VDD and LS_VDD (1) 2.7V to 5.5V D_VDD 1.7V to 2.0V I/O_VDD 1.6V to 4.5V (1) LS_VDD need to be the highest voltage than A_VDD, D_VDD, and I/O_VDD. For proper power supply sequence, LS_VDD need to be applied first. ELECTRICAL CHARACTERISTICS: A_VDD = LS_VDD = 3.3V; D_VDD = I/O_VDD = 1.8V (1) (2) The following specifications apply for RL(LS) = 8Ω, RL(HP) = 32Ω, f = 1kHz, unless otherwise specified. Limits apply for TA = 25°C. LM49350 Units Symbol Parameter Conditions (Limits) Typical(3) Limit(4) DC CHARACTERISTICS (Digital current combines D_VDD and I/O_VDD.

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) Typical values represent most likely parametric norms at TA = +25ºC, and at the Recommended Operation Conditions at the time of product characterization and are not ensured. (4) Datasheet min/max specification limits are specified by test or statistical analysis. 10 Submit Documentation Feedback Copyright © 2008–2012, Texas Instruments Incorporated Product Folder Links: LM49350 LM49350RLEVAL |
