Headphone Ground
Inverting Charge-Pump Output. Bypass to HPGND with a 1µF ceramic capacitor.
Noninverting Charge-Pump Output. Bypass to HPGND with a 1µF ceramic capacitor.
Left-Channel Headphone Output
Headphone Amplifier Ground Sense. Connect to the headphone jack ground terminal or
connect to ground.
Right-Channel Headphone Output
Jack detection Input. Connect to the microphone terminal of the headset jack to detect
jack activity.
Positive Earpiece Amplifier Output/Left Line Output
Negative Earpiece Amplifier Output/Right Line Output
Right Speaker Amplifier Ground
Negative Right-Channel Class D Speaker Output
Positive Right-Channel Class D Speaker Output
Right Speaker Power Supply. Bypass to SPKRGND with a 1µF capacitor.
Left Speaker and Microphone Bias Power Supply. Bypass to SPKLGND with a 1µF
capacitor.
Negative Left-Channel Class D Speaker Output
Positive Left-Channel Class D Speaker Output
Left Speaker Amplifier Ground.
Positive Differential Microphone 1 Input or single-ended Line Input 2. AC-couple with a
series 1µF capacitor. Can be retasked as a digital microphone clock output.
Negative Differential Microphone 1 Input or single-ended Line Input 1. AC-couple with a
series 1µF capacitor. Can be retasked as a digital microphone data input.
Negative Differential Microphone 2 Input or single-ended Line Input 3. AC-couple with a
series 1µF capacitor.
Positive Differential Microphone 2 Input or single-ended Line input 4. AC-couple with a
series 1µF capacitor.
Low-Noise Bias Voltage. The bias voltage is programmable. An external resistor in the
2.2kΩ to 1kΩ range should be used to set the microphone current.
Converter Reference. Bypass to AGND with a 2.2µF capacitor.
Common-Mode Reference Voltage. Bypass to AGND with a 1µF capacitor.
Analog Ground.
Analog Power Supply. Bypass to AGND with a 1µF capacitor.
Digital Power Supply. Bypass to DGND with a 1µF capacitor.
Digital Audio Interface Power-Supply Input. Bypass to DGND with a 1µF capacitor.
