3. V_in = [(V_{FS Max} - V_{FS Min}) - 1.6 V] V_p-p, 1 kHz, Volume = 0 dB.
Note that for (VA+) = -(VA-) = 9 V, V_in = 13.7 V_p-p = 4.8 V_RMS.
4. Measured with input grounded and volume = 0 dB. Will increase as a function of volume settings >0 dB.
5. Power-down is defined as RESET = low, all clock and data lines held static, and no analog input signals
applied.
