Usage Notes
When power is first applied, the states of the internal analog switches will be undefined. Applications must provide
external muting until the control data has been transferred and the switches set to appropriate states.
Applications should transfer both the left and right channel initial settings data before releasing the muting function
when initializing this IC after first applying power.
Applications should cover the CL, DI, and CE pin lines with the ground pattern, or should use shielded cables for these
lines to prevent the high-frequency digital signals transmitted over these lines from entering analog signal system.
When the oscillation occurs, connect a resistor of at least 200
to LOUT and ROUT pins.
