Negative Right-Channel Class D Speaker Output
Right-Speaker Ground
Left-Speaker, REF, Receiver Amp Power Supply. Bypass to SPKLGND with a 1FF and a
10FF capacitor.
Positive Left-Channel Class D Speaker Output
Negative Left-Channel Class D Speaker Output
Positive Receiver Amplifier Output or Left Line Output. Can be positive bypass switch input
when receiver amp is shut down.
Headphone Power Supply. Bypass to HPGND with a 1FF capacitor.
Inverting Charge-Pump Output. Bypass to HPGND with a 1FF ceramic capacitor.
Headphone Ground
Negative Receiver Amplifier Output or Right Line Output. Can be negative bypass switch
input when receiver amp is shut down.
Charge-Pump Flying Capacitor Positive Terminal. Connect a 1FF ceramic capacitor
between C1N and C1P.
Charge-Pump Flying Capacitor Negative Terminal. Connect a 1FF ceramic capacitor
between C1N and C1P.

connect to ground.
Left-Channel Headphone Output
S1 Digital Audio Bit Clock Input/Output. BCLKS1 is an input when the ICs are in slave mode
and an output when in master mode. The input/output voltage is referenced to DVDDS1.
S1 Digital Audio Serial-Data ADC Output. The output voltage is referenced to DVDDS1.
S1 Digital Audio Left-Right Clock Input/Output. LRCLKS1 is the audio sample rate clock
and determines whether S1 audio data is routed to the left or right channel. In TDM mode,
LRCLKS1 is a frame sync pulse. LRCLKS1 is an input when the IC is in slave mode and an
output when in master mode.
Single-Ended Line Input B2. Also positive differential line input B.
Right-Channel Headphone Output
S1 Digital Audio Interface Power-Supply Input. Bypass to DGND with a 1FF capacitor.
Master Clock Input. Acceptable input frequency range is 10MHz to 60MHz.
S1 Digital Audio Serial-Data DAC Input. The input/output voltage is referenced to DVDDS1.
The input voltage is referenced to DVDDS1.
