Note:
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
(±FS = ±(VRADH-VRADL) × 0.4).
4. Specified for L and R of each DAC.
5. The full-scale voltage (0 dB) and output voltage are proportional to VRDAH voltage.
Analog output voltage (Typ. @ 0 dB) = 2.95 Vpp*VRDAH/5
