CS42406

DC ELECTRICAL CHARACTERISTICS GND = 0 V; all voltages with respect to GND.

Notes: 14. Normal operation is defined as RST = HI with a 997 Hz, 0 dBFS digital input sampled at the highest Fs

for each speed mode, and open outputs, unless otherwise specified. Analog inputs are driven with a 1

kHz, -1 dBFS sine wave and sampled at the highest Fs for each speed mode.

15. IDT measured with no external loading on pin 14 (SDA).

16. Power Down Mode is defined as DAC_RST = LO, PDN_ADC = LO, with all clocks and data lines held

static.

17. Valid with the recommended capacitor values on FILT+ and VQ as shown in Figure 33.
