8 / 32 page  TAS5631B SLES263 – NOVEMBER 2010 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 TAS5631B power stage. PCB and system configurations are in accordance with recommended guidelines. Audio frequency = 1 kHz, PVDD_X = 50 V, GVDD_X = 12 V, RL = 4 Ω, fS = 384 kHz, ROC = 22 kΩ, TC = 75°C; output filter: LDEM = 7 mH, CDEM = 680 nF, MODE = 000, unless otherwise noted.
