Note 6. Measured by Audio Precision System Two Cascade.
Note 7. Analog In to TVOUT. Path : AINL+/− (AINR+/−) → TVOUTL (TVOUTR)
Note 8. Between TVOUTL and TVOUTR with analog inputs (AINL/R+/−) 1kHz/0dB.
Note 9. THD+N : −80dB(min. at 2Vrns).
Note 10. Analog input voltage by LIN/RIN pins (0dB). Stereo output (typ@0dBFS) = 2Vrms × VD/5.
Do not output signals over 3Vrms.
Note 11. The PSR is applied to VD with 1kHz, 100mV.
