(Unless otherwise specified, Ta = 25 C; AVDD, DVDD, AVB, DVB = 5.0 V; VRADH = AVDD, VRADL = AVSS,
VRDAH = AVDD, VRDAL = AVSS; fs = 44.1 kHz; BITCLK = 64 fs ; XTI = 256 fs;
Signal frequency 1 kHz; measuring frequency = 10 Hz to 20 kHz; 20 bits; DSP section in the reset state; ADC
with all ifferential inputs )
1. Single end input will result in poorer characteristics.
2. Indicates S/(N+D) when -60 dB signal is input.
3. The full scale for analog input voltage ( AIN = (AIN+) - (AIN-)) can be represented By
4. Specified for L and R of each DAC.
5. The full-scale voltage (0 dB) and output voltage are proportional to VRDAH voltage.
(±FS = ±(VRADH-VRADL) × 0.4).
Analog output voltage (Typ. @ 0 dB) = 2.95 Vpp*VRDAH/5
