ELECTRICAL CHARACTERISTICS
SLAS557B – SEPTEMBER 2007 – REVISED OCTOBER 2007
AUDIO SPECIFICATIONS (PBTL) (continued)
Audio performance is recorded as a chipset consisting of a TAS5518 pwm processor (modulation index limited to 97.7%) and
a TAS5342 power stage. PCB and system configuraton are in accordance with recommended guidelines. Audio frequency =
1kHz, PVDD_x = 31.5 V, GVDD_x = 12 V, RL = 3 , fS = 384 kHz, ROC = 27 k, TC = 75°C, Output Filter: LDEM = 10 μH, CDEM
= 1.0 uF, unless otherwise noted.
