Notes: 13. Normal operation is defined as RST = HI with a 997 Hz, 0 dBFS digital input sampled at the highest F
s
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 F for each speed mode.
s
14. I measured with no external loading on pin 14 (SDA).
DT
15. Power Down Mode is defined as DAC_RST = LO, PDN_ADC = LO, with all clocks and data lines held
static.
16. Valid with the recommended capacitor values on FILT+ and VQ as shown in Figure 33.
