8 / 26 page  TAS5612 SLAS682 – NOVEMBER 2009 www.ti.com AUDIO CHARACTERISTICS (BTL) Audio performance is recorded as a chipset consisting of a TAS5518 PWM Processor (modulation index limited to 97.7%) and a TAS5612 power stage. PCB and system configurations are in accordance with recommended guidelines. Audio frequency = 1kHz, PVDD_X = 32.5V, GVDD_X = 12V, RL = 4Ω, fS = 384 kHz, ROC = 30kΩ, TC = 75°C, Output Filter: LDEM = 7μH, CDEM = 680nF, MODE = 000, unless otherwise noted. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT RL = 3Ω, 10% THD+N (ROC=22kΩ, add Schottky 165 diodes from OUT_X to GND_X) RL = 4Ω, 10% THD+N 125 PO Power output per channel W RL = 3Ω, 1% THD+N (ROC=22kΩ, add Schottky 130 diodes from OUT_X to GND_X) RL = 4Ω, 1% THD+N 105 THD+N Total harmonic distortion + noise 1 W 0.03% Vn Output integrated noise A-weighted, TAS5518 Modulator 114 μV |VOS| Output offset voltage No signal 20 30 mV SNR Signal-to-noise ratio(1) A-weighted, TAS5518 Modulator 103 dB A-weighted, input level –60 dBFS using TAS5518 DNR Dynamic range 103 dB modulator Power dissipation due to Idle losses Pidle PO = 0, 4 channels switching (2) 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. 8 Submit Documentation Feedback Copyright © 2009, Texas Instruments Incorporated Product Folder Link(s): TAS5612 |
