EVAL-ADAU1860
Description
Used to connect I
C Address 1 and SPI data input to the ADAU1860, or
2
to connect UART data receiver to the ADAU1860.
Input and output header for serial audio signals.
Input and output header for serial audio signals.
Used to select ADDR0_SS or IOVDD for the ADAU1860. ADDR0 is I
Address 0, and SS is the SPI latch signal.
Used to select SCL_SCLK or GND for the ADAU1860. SCL is I
and SCLK is the SPI clock.
2
Used to connect I
C data and SPI data output to the ADAU1860, or to
connect the UART data transmitter to the ADAU1860.
Header that allows PDM interface devices to be connected to the EVAL-
ADAU1860EBZ.
Used to select between the on-board oscillator or an external clock signal
to connect to the ADAU1860, and it must be used with P27.
Default differential input pins connection.
Default differential input pins connection.
Default differential input pins connection.
Used to select single-ended input or differential input (AINP1 connects to
GND).
Used to select single-ended input or differential input (AINP2 connects to
GND).
Used to select single-ended input or differential input (AINP1 connects to
CM).
Used to select single-ended input or differential input (AINP2 connects to
CM).
Header that allows external headphone loads to be connected to the
EVAL-ADAU1860EBZ.
Used to select between the external source or the 1.8 V on-board LDO
regulator for the AVDD and HPVDD.
Used to select between the external source or on-board LDO regulator for
DVDD.
Used to select between the external HPVDD_L source or the on-board
LDO regulator for HPVDD_L.
Header that connects the external flash to the ADAU1860. When using
the external flash, connect P49 to P54 and disconnect P55 to P58.
UART communication with level shift.
USB 5 V power and communication.
Header that allows the external digital microphones to be connected to
the EVAL-ADAU1860EBZ.
Used to select AVDD or GND to REG_EN.
Connect P25 to disable the oscillator.
Used to select IOVDD or GND to SELEFBOOT_MP19.
Used to select the signal from P8 or the on-board crystal as the XTALI/
MCLKIN.
Used to select IOVDD or GND to ROM_BOOT_MODE_MP21.
Differential output.
Used to connect the external AVDD supply to the EVAL-ADAU1860EBZ.
Used to connect the external IOVDD supply to the EVAL-ADAU1860EBZ.
