NOTES: (1) Pins 8, 13, 14, 15, 16: VBUS, TEST3 TEST2 TEST1, TEST0. (2) Pin1: XTI. (3) Pins 10, 11, 12, 28: PLYBCK, SSPND, ZERO, XTO. (4) The dynamic

performance is based upon ideal host signal quality, and may vary according to the system. Dynamic performance specifications are tested using a Shibasoku #725

THD Meter with 400Hz HPF, 30kHz LPF, Average Mode, and 20kHz Bandwidth limiting. The load connected to the analog output is 5k

Ω, or larger, via AC coupling.
