10 / 48 page CS42L50 10 DS544PP1 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: 13. Power Down Mode is defined as RST = LO with all clocks and data lines held static. 14. Valid with the recommended capacitor values on FILT+_ADC, FILT+_DAC, VQ_DAC, and VQ_ADC as shown in Figure 4. 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. A small ceramic capacitor in parallel with a larger electrolytic is recommended.
