Note 8. (LIN+) – (LIN-) or (RIN+) – (RIN-); this value is proportional to VREFH voltage.
Note 9. PSR is applied to AVDD, DVDD and TVDD with 1kHz, 50mVpp. VREFH pin is held +5V.
Note 10. VREFH is held +5V, the input bias voltage is set to AVDD1, AVDD2 x 0.5. The 1kHz, 1.52Vpp signal is applied
to LIN- and LIN+ with same phase (e.g. shorted) or RIN- and RIN+. The CMRR is measured as the attenuation
level from 1.52Vpp = -7dBFS.
Note 11. S/N measured by CCIR-ARM is 98dB(@fs=48kHz).
Note 12. S/N measured by CCIR-ARM is 102dB(@fs=48kHz).
