8 / 41 page  TAS5612LA SLAS847A – MAY 2012 – REVISED MARCH 2015 www.ti.com 6.6 Audio Specification Stereo (BTL) Audio performance is recorded as a chipset consisting of a TASxxxx PWM Processor (modulation index limited to 97.7%) and a TAS5612LA power stage with PCB and system configurations in accordance with recommended guidelines. Audio frequency = 1 kHz, PVDD_X = 32.5 V, GVDD_X = 12 V, RL = 4 Ω, fS = 384 kHz, ROC = 24 kΩ, TC = 75°C, Output Filter: LDEM = 10 μH, CDEM = 1 µF, unless otherwise noted. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT RL = 4 Ω, 10% THD+N 125 PO Power output per channel W RL = 4 Ω, 1% THD+N 105 THD+N Total harmonic distortion + noise 1-W, 1-kHz signal 0.05% Vn Output integrated noise A-weighted, AES17 measuring filter 180 μV VOS Output offset voltage No signal 10 20 mV SNR Signal-to-noise ratio(1) A-weighted, AES17 measuring filter 105 dB DNR Dynamic range A-weighted, –60 dBFS (rel 1% THD+N) 105 dB Power dissipation due to idle losses Pidle PO = 0, channel switching (2) 1.2 W (IPVDD_X) (1) SNR is calculated relative to 1% THD-N output level. (2) Actual system idle losses also are affected by core losses of output inductors. 6.7 Audio Specification 4 Channels (SE) Audio performance is recorded as a chipset consisting of a TASxxxx PWM Processor (modulation index limited to 97.7%) and a TAS5612LA power stage with PCB and system configurations in accordance with recommended guidelines. Audio frequency = 1 kHz, PVDD_X = 32.5 V, GVDD_X = 12 V, RL = 4 Ω, fS = 384 kHz, ROC = 24 kΩ, TC = 75°C, Output Filter: LDEM = 10 μH, CDEM = 1 µF, CDCB = 470 µF, unless otherwise noted. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT RL = 3 Ω, 10% THD+N 43 PO Power output per channel W RL = 3 Ω, 1% THD+N 35 THD+N Total harmonic distortion + noise 1-W, 1-kHz signal 0.04% Vn Output integrated noise A-weighted, AES17 measuring filter 180 μV SNR Signal-to-noise ratio A-weighted, AES17 measuring filter 102 dB A-weighted, –60 dBFS (rel 1% DNR Dynamic range 102 dB THD+N) Power dissipation due to Idle losses Pidle PO = 0, channels switching (1) 1.2 W (IPVDD_X) (1) Actual system idle losses also are affected by core losses of output inductors. 8 Submit Documentation Feedback Copyright © 2012–2015, Texas Instruments Incorporated Product Folder Links: TAS5612LA |
