Description
Right Headphone Output.
Left Headphone Output.
Mono Output or Virtual Ground for Capless Headphone.
Analog Ground. The AGND and DGND pins can be tied together on a common ground
plane. AGND should be decoupled to AVDD with a 100 nF capacitor.
1.8 V to 3.3 V Analog Supply for ADC, Output Driver, and Input to Digital Supply Regulator.
This pin should be decoupled locally to AGND with a 100 nF capacitor.
Digital Core Supply Decoupling Point. The digital supply is generated from an on-board
regulator and does not require an external supply. DVDDOUT should be decoupled to
DGND with a 100 nF capacitor and a 10 μF capacitor.
Digital Ground. The AGND and DGND pins can be tied together on a common ground
plane. DGND should be decoupled to DVDDOUT and to IOVDD with 100 nF capacitors
and 10 μF capacitors.
