Notes: 8. In case of single ended input, S/(N+D)=80dB(typ, @AVDD=5V, fs=44.1kHz).
9. S/N measured by CCIR-ARM is 98dB(@fs=44.1kHz).
10. Full scale input for each AIN+/- pin is 1.5Vpp in differential mode.
11. Input resistance is 14k
typically at fs=96kHz.
12. PSR is applied to AVDD, DVDD and TVDD with 1kHz, 50mVpp. VREFH pin is held a constant voltage.
13. S/N measured by CCIR-ARM is 102dB(@fs=44.1kHz).
14. DVDD=TBDmA, TVDD=TBDmA(typ).
15. In the power-down mode. All digital input pins including clock pins (MCLK, BICK, LRCK) are held DVSS.
