Note: 3. This voltage is input to AIN+ and AIN- pin, and is proportional to VREF. Vin = 0.56 x VREF.
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.
