Notes: 8. Normal operation is defined as RST = HI with a 997 Hz, 0dBFS input sampled at Fs = 48kHz, and open
outputs, unless otherwise stated.
9. Power Down Mode is defined as RST = LO with all clocks and data lines held static.
10. Valid with the recommended capacitor values on FILT+ and VQ_HP as shown in Figure 1. Increasing
the capacitance will also increase the PSRR. NOTE: Care should be taken when selecting capacitor
type, as any leakage current in excess of 1.0 µA will cause degradation in analog performance.
11. To prevent clipping the outputs, VA_HPMIN is limited by the Full-Scale Output Voltage VFS_HP, where
VA_HP must be 200 mV greater than VFS_HP. However, if distortion is not a concern, VA_HP may be
as low as 0.9 V at any time.
