ELECTRICAL CHARACTERISTICS
SLES188 – AUGUST 2006
Audio frequency = 1 kHz, PVDD_x = 50 V, GVDDx = 12 V, VDD = 12 V, R
L = 8 , fs = 384 kHz, OC_ADJ = 22 k,
T
C = 75°C, output filter is LDEM = 10 H, CL = 1 F (unless otherwise noted). AC performance is recorded as a chipset,
TAS5518 as front end with an effective modulation index of 96.1% and TAS5261 as the power stage. PCB and system
configuration are in accordance with recommended design guidelines.
