Power Supply Rejection Ratio (Note 9)
9. Valid with the recommended capacitor values on FILT+, VQ_LINE and VQ_HP as shown in Figure 6.
Increasing the capacitance will also increase the PSRR. Note that care should be taken when selecting
capacitor type, as any leakage current in excess of 1.0 µA will cause degradation in analog
performance.
