Signal Frequency=1kHz; 24bit Data; Measurement Frequency=20Hz 20kHz at fs=44.1kHz, 20Hz~40kHz at fs=96kHz;
unless otherwise specified)
Normal Operation (PDN = “H”)
Power-down mode (PDN = “L”)
AVDD
DVDD+TVDD 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.
9. S/N measured by CCIR-ARM is 98dB(@fs=44.1kHz).
8. In case of single ended input, S/(N+D)=80dB(typ, @AVDD=5V, fs=44.1kHz).
