Description
Analog Ground Pin. The AGND, DGND, and PGND pins can be tied directly
together in a common ground plane. AGND should be decoupled to an
AVDD pin with a 100 nF capacitor.
Analog Audio Input 1. 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.
ADC Reference Current. The full-scale current of the ADCs can be set with an
external 18 kΩ resistor connected between this pin and ground.
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.
Active Low Reset Input. Reset is triggered on a high-to-low edge, and the
ADAU1401 exits reset on a low-to-high edge. For more information about
initialization, see the Power-Up Sequence section.
Enable/Disable Self-Boot. SELFBOOT selects control port (low) or self-boot
(high). Setting this pin high initiates a self-boot operation when the ADAU1401
is brought out of a reset. This pin can be tied directly to the control voltage
or pulled up/down with a resistor.
I
2
C and SPI Address 0. In combination with ADDR1, this pin allows up to four
ADAU1401s to be used on the same I
2
C bus and up to two ICs to be used
with a common SPI CLATCH signal.
Multipurpose GPIO or Serial Input Port LRCLK (INPUT_LRCLK).
Multipurpose GPIO or Serial Input Port BCLK (INPUT_BCLK).
Multipurpose GPIO or Serial Input Port Data 1 (SDATA_IN0).
Multipurpose GPIO or Serial Input Port Data 0 (SDATA_IN1).
Digital Ground Pin. The AGND, DGND, and PGND pins can be tied directly
together in a common ground plane. DGND should be decoupled 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. DVDD should be
decoupled to DGND with a 100 nF capacitor.
