Power-up Sequences
1. Hold RESET low while the power supplies are turned on.
2. Set the I²S/LJ, 1_2VRMS, and DEM configuration pins to the desired state.
3. Provide the correct MCLK, LRCK, and SCLK signals locked to the appropriate frequencies as
4. After the power supplies, configuration pins, and clock signals are stable, bring RESET high. The

2. Set the I²S/LJ, 1_2VRMS, and DEM configuration pins to the desired state.
3. After the power supplies and configuration pins are stable, provide the correct MCLK, LRCK, and
Power-down Sequences
1. For minimal pops, set the input digital data to zero for at least 8192 consecutive samples.
2. Bring RESET low.
3. Remove the power supply voltages.
1. For minimal pops, set the input digital data to zero for at least 8192 consecutive samples.
2. Remove the MCLK signal without applying any glitched pulses to the MCLK pin.
3. Remove the power supply voltages.
Note:
MCLK signal duty cycle specification and the nominal frequency of the input MCLK signal. A transient may
occur on the analog outputs if the MCLK signal duty cycle specification is violated when the MCLK signal
is removed during normal operation; see

The sequence will complete and audio will be output from the AOUTx pins within 50 ms after valid
clocks are applied.
A glitched pulse is any pulse that is shorter than the period defined by the minimum/maximum
