LAYOUT RECOMMENDATIONS
PARTS PLACEMENT
The ADC input voltage-to-current resistors and the ADC current
set resistor should be placed as close as possible to the 2, 3, and
4 input pins.
All 100 nF bypass capacitors, which are recommended for every
analog, digital, and PLL power/ground pair, should be placed as
close as possible to the ADAU1401. The 3.3 V and 1.8 V signals
on the board should also each be bypassed with a single bulk
capacitor (10 μF to 47 μF).
Rev. 0 | Page 47 of 52
All traces in the crystal oscillator circuit (Figure 14) should be
kept as short as possible to minimize stray capacitance. In addition,
avoid long board traces connected to any of these components
because such traces may affect crystal startup and operation.
GROUNDING
A single ground plane should be used in the application layout.
Components in an analog signal path should be placed away
from digital signals.
