Low-Power, Stereo Audio Codec
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 and a 10FF 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.
Noninverting Charge-Pump Output. Bypass to HPGND with a 1FF ceramic capaci-
tor.
Positive Right-Channel Class D Speaker Output
Right-Speaker Power Supply. Bypass to SPKRGND with a 1FF capacitor.
Left-Speaker Ground
No Connection
Headphone Amplifier Ground Sense. Connect to the headphone jack ground
terminal for optimal performance or connect to PCB ground.
Left-Channel Headphone Output
S1 Digital Audio Bit Clock Input/Output. BCLKS1 is an input when the IC is 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
