Note 8. Inter-channel isolation between ALINE_IN and ANE_IN at –1dB FS signal input.
Note 9. The full scale for analog input voltage is FS = (VREFH-VREFL) ∗ 0.6.
Note 11. Full scale output voltage when VREFH = AVDD, VREFL = AVSS.
MS0697-E-00-PB
Note 7. S/(N+D) when -60dB signal is applied.
Note 10. Between ANE_OUT and ALINE_OUT.
(Ta = 25°C; AVDD=DVDD = 3.3V; VREFH = AVDD, VREFL = AVSS;
BITCLK = 64fs; Signal frequency 1kHz; Measurement frequency = 20Hz to 3.4 kHz; fs = 8kHz;
