Notes: 8. S/N measured by CCIR-ARM is 98dB(@fs=44.1kHz).
9. Input resistance is 16kΩ typically at fs=96kHz.
10. PSR is applied to AVDD, DVDD and TVDD with 1kHz, 50mVpp. VREFH pin is held a constant voltage.
11. S/N measured by CCIR-ARM is 102dB(@fs=44.1kHz).
12. TVDD=0.1mA(typ).
13. In the power-down mode. All digital input pins including clock pins (MCLK, BICK, LRCK) are held DVSS.
