SLAS846A â MAY 2012 â REVISED MARCH 2015
6.6 Audio Specification Stereo (BTL)
Audio performance is recorded as a chipset consisting of a PWM Processor (modulation index limited to 97.7%) and a
TAS5614LA power stage with PCB and system configurations in accordance with recommended guidelines. Audio frequency
= 1 kHz, PVDD_X = 36 V, GVDD_X = 12 V, RL = 4 â¦, fS = 384 kHz, ROC = 24 kâ¦, TC = 75°C, Output Filter: LDEM = 10 μH,
CDEM = 1 µF, unless otherwise noted.
