NOTES: 1. The following voltages were applied to the SD16 inputs:
V_IN,A+(t) = 1.2V + V_PP/2 × sin(2π × f_IN × t)
V_IN,A−(t) = 1.2V − V_PP/2 × sin(2π × f_IN × t)
resulting in a differential voltage of V_diff = V_IN,A+(t) − V_IN,A−(t) = V_PP × sin(2π × f_IN × t)
2. The SINAD performance of the SD16_A maybe degraded. See errata sheet.
