(1)

When the TAS3218 is operated in slave mode, the internal analog clocks for ADC and DAC are derived from external MCLKIN input. In

this case, the analog performance will depend on MCLKIN quality (i.e., jitter, phase noise, etc.).

(2)

16- series resistor required in L and R headphone outputs for short-circuit protection.
