Description
Analog Ground Pin. The AGND, DGND, and PGND pins can be tied directly together in a
common ground plane. Decouple AGND to an AVDD pin with a 100 nF capacitor.
Analog Audio Input 0. Full-scale 100 μA rms input. Current input allows input voltage level
to be scaled with an external resistor. An 18 kΩ resistor gives a 2 V rms full-scale input. See
the Audio ADCs section for details.
ADC Reference Current. Set the full-scale current of the ADCs with an external 18 kΩ resistor
connected between this pin and ground. See the Audio ADCs section for details.
Analog Audio Input 1. Full-scale 100 μA rms input. Current input allows the input voltage
level to be scaled with an external resistor. An 18 kΩ resistor gives a 2 V rms full-scale input.
Active Low Reset Input. Reset is triggered on a high-to-low edge, and the ADAU1701 exits
reset on a low-to-high edge. For more information about initialization, see the Power-Up
Sequence section for details.
Enable/Disable Self-Boot. SELFBOOT selects control port (low) or self-boot (high). Setting
this pin high initiates a self-boot operation when the ADAU1701 is brought out of a reset. This
pin can be tied directly to the control voltage or pulled up/down with a resistor. See the
Self-Boot section for details.

Digital Ground Pin. The AGND, DGND, and PGND pins can be tied directly together in a
common ground plane. Decouple DGND to a DVDD pin with a 100 nF capacitor.
1.8 V Digital Supply. This can be supplied either externally or generated from a 3.3 V supply
with the on-board 1.8 V regulator. Decouple DVDD to DGND with a 100 nF capacitor.
