EVALUATION BOARD STARTUP
To start up the evaluation board using single supply, follow
these steps:
1.
Ensure that the output filter is installed or 0 Ω links are in
place to connect the output terminals to the IC.
2.
Place a jumper between the upper two pins of J9 (REG_EN
to PVDD) to enable the on-chip 1.8 V regulator.
a.
In the bottom right corner, place a jumper across the
bottom pins of J11, and open J4 (ADDR pull-down to
GND) to select the device I

C address of 0x28, or 0x14
if using the Aardvark adapter.

S/TDM output, select the _EXT signal
paths on P12 and connect digital audio signals via the
Audio Precision connection to P2. Note that P5 allows
multiple evaluation boards to be daisy-chained to the same
signal bus.
4.
Insert jumpers across all three rows of H2 to establish
direct connection of the digital audio signal lines to the
inputs of the
. For special use cases, to minimize
stub length, remove the jumpers across H2 and source
digital audio signals directly to the ports of H1.
5.
If using the on-board SPDIF-to-I

S converter instead of
the external digital audio port for Audio Precision, insert
jumpers across JP1 and the bottom two terminals of P1
(IOVDD to 1V8) to power the level translators for digital
audio signals.
