5 / 31 page LM49153 www.ti.com SNAS496C – JANUARY 2011 – REVISED MAY 2013 Electrical Characteristics VDD = 3.6V, HPVDD = 1.8V (1) (2) The following specifications apply for VDD = LSVDD, AV = 0dB, RL = 15μH+8Ω+15µH (Loudspeaker), RL = 32Ω (Headphone), CSET = 0.1µF, f = 1kHz, ALC off, unless otherwise specified. Limits apply for TA = 25°C. (3).

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) Loudspeaker 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 = 4Ω, the load is 15µH + 4Ω + 15µH. (4) 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 specified. (5) Datasheet min/max specification limits are specified by test or statistical analysis.
