SNR is calculated relative to 0-dBFS input level.

(2)

Actual system idle losses are affected by core losses of output inductors.

6.7 Audio Specifications (Single-Ended Output)

Audio performance is recorded as a chipset consisting of a TAS5086 PWM processor (modulation index limited to 97.7%)

and a TAS5352A power stage. PCB and system configuration are in accordance with recommended guidelines. Audio

frequency = 1 kHz, PVDD_x = 34.5 V, GVDD_x = 12 V, RL = 4 Ω, fS = 384 kHz, ROC = 22 kΩ, TC = 75°C, output filter: LDEM =

20 μH, CDEM = 1 μF (unless otherwise noted).
