(Ta=25°C; VA, VD, VT=5.0V; AGND=DGND=0V; VREF=VA; fs=44.1kHz; Signal Frequency =1kHz; 24bit Data;
Note: 3. This voltage is input to AIN+ and AIN− pin, and is proportional to VREF. Vin = 0.56 x VREF.
MS0011-E-01
Measurement frequency = 20Hz ∼ 20kHz at fs=44.1kHz, 40Hz ∼ 40kHz at fs=96kHz; unless otherwise specified)

4. Measured by Figure 12. DC Bias Voltage, Vb = 4.7k / (3.3k + 4.7k) x VA = 0.5875VA.
5. PSR is applied to VA, VD, VT with 1kHz, 50mVpp. VREF pin is held a constant voltage.
6. Full scale (0dB) of the output voltage when summing the differential outputs, AOUT+/− by unity gain.
This voltage is proportional to VREF. Vout=1.08 x VREF x Gain.
