4. Normal operation is defined as RST = HI with a 997 Hz, 0 dBFS input.
5. Current consumption increases with increasing XTAL clock rates and PWM switch rates. Variance be-
tween DAI clock rates is negligible.
6. ILC measured with no external loading on the SDA pin.
7. Valid with PSRR function enabled and the recommended external ADC (CS4461) and filtering.
8. Power down mode is defined as RST pin = LOW with all clock and data lines held static.
9. When RST pin = LOW, the internal oscillator is active to provide a valid clock for the SYS_CLK output.
