8 / 40 page CS43L42 8 DS481PP2 POWER AND THERMAL CHARACTERISTICS (GND = 0 V; All voltages with respect to ground. All measurements taken with all zeros input and open outputs, unless otherwise specified.) Notes: 8. Power Down Mode is defined as RST = LO with all clocks and data lines held static. 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.
